I've been a member of ebay for more than 5 years and I'm very happy with the services. Sometimes the shipping takes too long but I guess it's because most of the sellers are from China ;)
My wife started drinking the Lida pills over 2 months ago. She lost 14 pounds in 5 weeks so I guess it's working. However she had some problems with her sleep but it lasted only 3-4 days.
Great site and customer service! I've ordered 3 shirts and one of them was too small. They changed it free of charge and sent me a gift - giant cup with their website on it! :)
My wife and I used their services for our Global Entry cards and everything was fine. Their fees are a little higher than what I expected but overall we're happy with the results.
