I have been shopping on Etsy for YEARS and only in the last 12 months or so have I gotten things that are obviously drop-shipped. I found a lovely bracelet in a listing that was just the right shape. It arrived last week and while it was silver in color, the "metal" was the same one you find in silver-colored plastic silverware. I complained, they refunded my purchase and didn't even ask for it back.
Anyway, when you check to see what reviews say, click on the reviewer. I'm finding that people are creating profiles to "like" products and talk about how happy they are with their purchase, but they're profiles that have no purchases recorded.
