One of the new changes when MCR re-launched it's website recently was a drastic lowering of the weekly code limit. It had been 120, dropped to 100, and has now fallen down to 75 points total. That's 25 three-point codes or seven 12-packs. Most people generally do not drink that much Coke in a week anyway, but I've seen some grumbling. Mainly because Coke did not warn of an impending drop and the site went down without much notice (as in a social media posting just a few hours, if that, before it went down for days). By then, the new rules had already gone into effect, again, without a heads-up since the social media post relating to the site maintenance was on 1/21 and the new rules began 1/20.
Note: The 75 point weekly limit does not include bonus points.
What you will see is a bit different rewards system, now tiered (site fully integrated into Beta), and there are some rewards that weren't otherwise available under MCR's original site (like Amazon.com gift cards, for example). Still, at 75 points a week, if you were accustomed to entering more codes (like your co-workers gave up their cap codes to you, for instance), the drop in entering will affect your ability to rack up points at a good clip.
75 x 52 = 3,900 possible per year if you entered faithfully each week
100 x 52 = 5,200 possible per year if you entered faithfully each week
Difference of -1,300 points
However, on a positive note, I did migrate to Beta a few months ago and enjoyed the Christmas rewards selection, snagging a few gift cards on the cheap. It is for this reason that I recommend you bank what you can and hope for a great offer, or at the very least, save those points for next Christmas. I was also able to snag the max coupons for free Coke at 30 points when the offer was live. Very nice and worth it to me to save up points for that alone.
