Prices are really attention grabbing, but some wish items are the cheapest of the cheap Chinese knockoffs. You get what you pay for it.
Shipping is the original slow boat from China if not a domestic seller. There are some domestic sellers with US items on there (e.g. some Harley apparel). One problem is that even with multiple buys, you usually do not get combined shipping. If you are using different sellers at one time, the shipping adds up pretty quick.
