Stop in for a cup of coffee

Why do auto parts and tool suppliers only send me coupons and advertising for things I've already purchased?

Seems in today's age they'd have some algorithm that would project the most likely next purchases.... instead of offering a coupon for brake cleaner after I just bought 3 cans.
Soggy start here. Should stop around noon and dry up by about the time I go in to work. :BangHead:
