I would much rather view ads served from online stores I have already shopped at, that I am more likely to click through and actually, you know, buy something, than see another of those spam/scam “<%=getzipcodefromhttpreferer%> Mom’s Seekrit Belly/Wrinkle/Work-at-Home Trick” ads
One of the local stores uses your “loyalty card” information to print up coupons for things you actually use. What a concept.
