best price, quick response.

First time buying here, process was smoth and fast.

It was gr8 and convinced

Shipped quicker than expected and best price I could find and shipped free. Will order from them again

so far so good....

The price was the best I found. It took way too long to finally ship (in my opinion) but FedEx got it here quickly so it worked out within my time frame. Overall, I would consider them again if the price is right and I'm not under time constraints
