Cheapest way to convert cash to coins on a weekly basis

[revs88]

Dear all,

Can anyone recommend a cost-effective route to get a weekly coinage float (£1, £2, 50p coins) of £500 per week for a small multi-site retailer.

Currently the 10+ shop managers are going to their local Post Office branches on a weekly basis and being charged a small fortune over the course of the year.

They've previously used the local branches of Barclays (the company's bank) but have stopped due to even higher fees.

Thanks, Richard
