Easy shopping

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.

So far so good.
