All good

I can’t see right now. I haven’t received my item. I just ordered it.

It all seemed pretty smooth so far. Hope it is delivered in a timely fashion.

Autoplicity had the part I needed at a reasonable price, so I ordered 2. Always good to have a spare for next time. It's the control panel for my RV refrigerator. The total was enough for free shipping, but they offered 2 day shipping for $10 extra. I chose the expedited delivery, since my fridge wasn't working. They packed and sent it the same day, but it took a week to get here. I don't say that as a complaint about them. I'm in the middle of nowhere, so I wasn't surprised that it took a week. When I asked for the extra delivery fee to be refunded, they refunded it right away. Anyway, the fridge is cooling again. I'm happy! :-)

It arrived on time packaging was very good...perfect transaction

No problem, so far.

I had a few small issues with logging into the site. I was not able to utilize and apply any coupons with my order this time. Anyway, the price and shipping are well within reason. When the product arrives and is installed, then I will be better able to write a relevant review. So far, so good, ordering has been easy.

I had a very hard time checking out

Quick and easy!
