Just processed the order. It was easy enough.

This was the only place that I could find the Champion Resistor Spark Plug that my weed wacker needed. Had a great experience in ordering and receiving product.

very good reliable website

Found what I was looking for... Cheaper than anywhere else...

Ordering was quick and easy. A lot of piece of mind being able to check out through Amazon. We'll see how the rest goes. (Shipment, correct product, customer service if needed, etc)

EXCELENT PRICE,FAST SHIPING!!! VERY SATISFIED THANKS ROD.<br>
