If you go to Morrisons you can buy 30 'Savers' economy bin liners for under 70p. South Gloucestershire Council, on the other hand, wants to charge you £20 for ten green recycling bags.
To rinse out more cash from local people, the Council wants to stick a sell-by date on each roll of bin liners - forcing residents' to renew every six months.%VIRTUAL-SkimlinksPromo%
£40 a year for 20 bags
The money-making ruse has upset some locals. To make matters even more expensive for local people, cash-strapped South Gloucestershire Council wants to charge residents an extra £36 a year to collect the waste - an additional surcharge on council tax already paid.
Like all councils, South Gloucestershire Council is attempting to save money. Its chief executive is Amanda Deeks, who in 2011 was on a salary of £155,000 a year (down from around £163,000 when Eric Pickles ordered council chief execs to take a 5% pay cut). She wants to see the council's waste strategy make £350,000 in savings.
"Charging will almost certainly exceed the £350,000 savings requirement that the waste service has to achieve," Councillor James Hunt complained to the Mail. "We've spent a long time encouraging people to recycle and this doesn't help matters."
In fact, the Council's own estimates on their website claim the full chargeable service could make up to £1.2m for the Council (if you're on income support the Council will give you a 50% discount on the garden bin liners, reducing their cost from £2 each to £1).
Though "Consultation is an important part of the decision making process," there appears to have been very little consultation here. In fact, their online consultation form only offers the chance for South Gloucestershire Council residents to give a view on a choice of possible tariffs. There is no space to disagree with the proposal.
What next? Charging extra to use the local library or to walk in the park?

Council to charge £20 for ten bin liners
Using a mobile phone to make and receive calls, send texts and browse the web while abroad can be extremely costly – especially if you are travelling outside the European Union (EU), where calls can cost up to 10 times as much as at home.
To avoid high charges, Carphone Warehouse suggests tourists ensure a data cap is in place, use applications to check data usage, turn off 'data roaming', avoid data-intensive applications such as Google Maps and YouTube and use wi-fi spots to update social networking sites.
Payment Protection Insurance (PPI) is supposed to help people to continue meeting their loan, mortgage or credit card repayments if they fall ill or lose their jobs. However, policies are often over-priced, riddled with exclusions and sold to people who could not make a claim if they needed to.
At one point, sale of this cover - which was often included automatically in loan repayments - was estimated to boost the banks' profits by up to £5 billion a year.
Now, though, consumers who were mis-sold PPI can fight back by complaining to the bank or lender concerned and taking their case to the Financial Ombudsman Service (08000 234567) should the response prove unsatisfactory.
It could be you, but let's face it, it probably won't be. In fact, buying a ticket for the Lotto only gives you a 1 in 13.9 million chance of winning the jackpot.
With odds like that, you would almost certainly be better off hanging on to your cash and saving it in a high-interest account.
No-frills airlines such as EasyJet may promote rock-bottom prices on their websites. But the overall fare you pay can be surprisingly high once extras such as luggage and credit card payment fees have been added - a process known as drip pricing.
Taking one piece of hold baggage on a return EasyJet flight, for example, adds close to £20 to the cost of your flight, while paying by credit card increases the price by a further £10.
It may therefore be worth comparing the total cost with that of a flight with a standard airline such as British Airways.
Cash advances, which include cash withdrawals, are generally charged at a much higher rate of interest than standard purchases.
While the average credit card interest rate is around 17%, a typical cash withdrawal of £500, for example, is charged at more than 26%.
What's more, as the interest accrues from the date of the transaction, rather than the next payment date, costs will mount up even if you clear your balance in full with your next payment.
Supermarkets such as Tesco and Asda often run promotions under which you can, for example, get three products for the price of two.
However, it is only worth taking advantage of these deals if you will actually use the products. Otherwise, you are simply buying for the sake of it, which is a waste of your hard-earned cash.
Buy a train ticket at the station on the day of travel and the price is likely to give you a shock - especially if you are travelling a long distance at a busy time of day.
However, you can cut the cost of train travel by 50% or more by going online and making the purchase beforehand - especially if you book 12 weeks in advance, which is when the cheapest tickets are on sale.
Other ways to reduce the price you pay include avoiding peak times and taking advantage of so-called carnet tickets, which allow you to buy, for example, 12 journeys for the price of 10.
Most High Street banks offer packaged accounts that come with monthly fees ranging from £6.50 up to as much as £40, with a typical account charging about £15 per month.
Various benefits, such as travel insurance and mobile phone insurance, are offered in return for this fee. But whether or not it is worth paying for them depends on your individual circumstances.
