I just received my Knn filter. Shipment was on time. The box look beat up and deformed with a lot of tapes but the filter seems to be in good condition.

Easy money

Great so far.

Purchased set of four Scribner 5 gallon utility jug. After doing considerable looking, Autoplicity had the lowest price by far in comparison to all other competitors. Communication has been great with items ordered shipped with tracking number the next day. Great buying experience.

Easy to find and price was good. The product fit well. Works well so far

Paypal payment was a little awkward but it looks like it worked

Best prices I have found. They got me a tracking number within 2 business days. Can't wait for my goods to arrive. Will be using this site again for sure.
