If you wanted only him to respond (where he presumably would've given you the same answer I did) you should have sent them a PM to ask how they did it... not posted on a public forum where other people may answer.
As to the comment that "Ain't nobody trying to buy 28 deodorants" while it may not be everyone... clearly I am not alone since the person you were responding to said they took advantage 10x. Cost me less than $98 to get $140 in Nintendo gift cards (would have been higher if I had gotten XBox insead. So it was well worth the effort for me. Plus I donated the Axe to my church as part of their grocery giveaway.
