My husband purchased the portable phone charger useful for when I'm traveling and don't have access to a USB port or a plug. I keep it in my purse and when my phone gets low, I plug it in. It helps give me a full extra battery cycle. They took a while to arrive, but they don't claim 2-day shipping so no big deal.
I then ordered the pink compression sleeves for running. They were half the price of the name brand ones, arrived quickly (less than week of my order), and they are a much tighter, durable material than the name brand ones. I believe because they are knit more tightly, they will withstand more laundry cycles and therefore a terrific deal.
My only warning would be about the shipping. I got the impression that it's not all coming from one warehouse, which might explain the discrepancies in shipping. I also wouldn't commit a ton of money to something like a tablet. But, I have no real reason for that besides that I like to buy high ticket items from places with a store-front or an online store with a proven track record of good customer service (a la Amazon).
Try it yourself and make your own decision, I'm thrilled we found this site!
