For starters, smart-shopping has nothing to do with going to the mall by a beautiful afternoon to see if a shop might have something that please our eyes...

Smart-shopping is a search, made by a shopper, with the aim of finding a merchant offering the best, in a precise criterion, which the shopper determined as being his (her) master criterion. The master criterion is the criterion that the shopper looks most to optimize (for example: lowest price, fastest shipping, etc.). This search is done over as many merchants as possible to get greater offers for a given product. The more merchants offering the same product, the more chances the shopper's master criterion has to be optimized and appealing.
