It's called shopping, not buying. If you can get me into your store but can't make the sale that's your fault.
I've gone into places just to shop and made purchases because of a good experience/deal/what-have-you. I've also gone into shops to purchase and had bad experiences that sent me elsewhere (online or across town).
And for the record, I love the big ski wall, unless it's a niche shop that stocks the majority of a niche and I happen to be looking for that niche.
I think you misunderstand me. Re-read what I wrote - I wasn't saying you had to buy if you went in and didn't find what you wanted, but it sucks if you go check out stuff and gather info in a shop with the intention of buying online.
