I know that people generally only write reviews when things don't go well, and I admit I am part of that group. I have been shopping at STP since 2006. They use to send out extra discounts and special deals. Now only free shipping. Never had an issue with shipping on-time until now. They stated it was an update of their system. But after another 2 days and still no shipment, I decided to look at some reviews. Sounds like they are slow to ship items. Didn't use to be this way. I know why Amazon is growing so fast. They still do have some good deals, but will consider other options when purchasing.
