For a small purchase, I got the beautiful shopping bag pictured above. Rarely do you think of shopping bags as cute but this one has an amazing animal-print. I'll re-use the bag again and again.
Upscale retailers know that offering attractive bags is part of the "experience" they offer shoppers. Many establishments distinguish themselves with instantly-recognizable packaging. Tiffany, for example, uses a unique color for its bags.
Do you notice shopping bags? Do they matter at all to where you choose to shop?
