Don't they want to see company letter heads, bills in the company name, registration with companies house / vat registration details?
CostCo are swine for that, they want to see all sorts before they'll give you a card. Hopefully Makro are a bit easier to get an account with??
Hhmmmm, if you don't have (or want I suppose) a Makro card, you can still get the shelves, but they're £29.88. Still not a bad price to be honest, but £20.39 would be much better
