Lot of sites do this. They know if you are still searching, you will find it cheaper... I often save stuff to cart at Advance Auto a week or so ahead just to get a discount. :)
Yup... I feel like a credit card hacker sometimes. I find a site with multiple items... I buy the cheapest one, and then, very often will receive a discount code or bonus for "Your next purchase". It's like playing slots
By the way.. Spoke with Classic Industries.... My order is being fulfilled. Apparently I snagged the last harness they had in stock. They should do it like eBay motors and tell you what the inventory is.
Anyhooo. That's motivation to get the engine bay prepped.
