I do coke points. Wait until around Christmas where they give away coke certificates for next to nothing. Also, dummy accounts are a good thing, but be clever enough to put micro tweaks in the address and change the name completely. I've lost about 3 accounts from stupidity. Done right, it pays off. I've walked out of Walmart With about $300 of cases of coke, completely filling a couple shopping carts.
I don't accumulate enough points for it to be worth having multiple accounts, and the 75 points a week thing has supremely devalued them (and it's really more like 73 points because who the hell buys six packs anymore).
People will trade the codes for ANYTHING these days if Ebay sales and Slickdeals are barometers of value. I'm going to be mildly surprised if Coke renews the program next year, to be honest.
Anyway, this is my second belt buckle, I got the first one in 2013. They retail for $150 and the first one cost 1,500 points. That was basically a $1 per 12 pack subsidy which I thought was doing pretty good. Certainly not for everyone but the shock value of ---my bottom--- walking around in one of these things is priceless. Plus the Houston Rodeo gave my wife money so we like them.
