Great product, fast shipping!!

Unbeleively fast shipping. I ordered on a Tuesday night, and it was delivered to my door by Thursday. Plus, the item was the cheapest with shipping on the web! I will most certainly be doing business with them again!

prices are good. After I paid it took them 5 days to ship the order. Communication is not very good with autoplicity.

Great selection and easy checkout! The only thing is I didnt get an email confirmation as soon as I order which made me wonder is the transaction went through. I did get an email once the items were shipped though.
