Quirky boutiques and bargain basements are quick to set up when you rent real estateon the high street. Empty units discourage shoppers and look dispiriting, so owners are eager to let vacant shops, and may be willing to negotiate terms and prices to suit you. Move your stock in, then just add an eyecatching window display and you're good to go. Rents in busy areas will be higher, but there will be more passing trade, while quieter parts of town will be less expensive, but more effort will be needed to attract customers.
