I have managed to achieve Gold membership, and I earned the chance to pick from a few rewards, and I picked a free 1 year subscription to Good Housekeeping magazine. I also get 20% off everything I buy for a year. I have also signed up for http://load2cardnow.com/ and can now upload coupons from the wellness site straight to my wellness+ card. You can also upload pictures and get a variety of discounts.
I shop at Rite Aid a lot, so it didn’t take very long for me to hit Gold, but it was worth it, because 20% is also the employee discount (I worked there for a bit).
