"is it true that one pepsi cost 1 pound ?"
If you go to Farmfoods (superstore), you can get 4 cans of Pepsi for £1 !!!.........well you can in Manchester anyway!
PS. I think you should be asking for at least £35,000 minimum........I would'nt go to London for anything less. You should also check out Manchester > cheap rent, cheap council tax, cheap curries, cheap travel & cheap Pepsi !!!!
All the best.
