Here, here, symptahize too with duties and in-store shopping! But retail IS changing. Right now big brands are actually trying to ENCOURAGE customers to come for the "experience" rather than some utilitarian need to actually get something (Think Lululemon, Apple stores, etc). So as lots of brick and mortar stores are still caught in this massive transition, I don't think a customer should feel bad about trying something in the store and ordering it from the internet, if it makes more sense money-wise for them. It is bad business from the brick and mortar store not to take this eventuality in consideration, and not to adapt and even use it to their advantage.
There is of course also the old mom and pop's store, and those, I think, will survive this change, although maybe in niche markets: as they pre-select items with considerations in mind, for example, health, comfort or catering to a precise segment of the population. They not only sell the product, but also convenience, which almost eliminates the need to go online and shop for yourself, since the whole point of buying at their store is to save time.
