I sent in for a $5 mail-in rebate on some beer & got this back:
"I am sorry that your rebate has not been processed. After further research, I verified the rebate could not be processed because per the guidelines the promotion AB-152 states: Save $5.00 on the purchase of one 12-pack or larger of Michelob Ultra (cans or bottles) and you purchased a 18-pack of Michelob Ultra bottle."
