Awesome!!

Everything was great from autoplicity, but Fed ex their tracking of shipment sucks. All it does is say shipped, then in transit, finally delivered, that isnt order tracking that's basically the shipping process, it said in transit for 3 days (of course) leaving me with no idea how close it is.

My product came in faster than I expected to receive it and I am happy about that.

like the price and the freight

Found what I needed and ordered quick and easy. PayPal is another great feature.

Great pricing and quick shipping. GREAT
