Listings for low cost items are great, but after ordering they are "Out of Stock" -- despite still appearing on the web pages as available at a higher rate. This has happened to multiple orders of mine. It seems like a "bait and switch" ordeal. Similarly, offers of "Free Shipping on Orders over $75" is also great -- but then there are "$1 extra fees" on many items. Why? The Free Shipping offer seems disingenuous or dishonest when you're tacking on an extra dollar to each items' list price. Billing is terrible (sending a notice that I have a "credit" amount with the company is not what I want. And very slow to refund payments on unfilled/undelivered/out of stock items. Overall, I've been very frustrated.
