PCHPoints has been around for a number of years and is only now closing. They have been prompt with reward redemptions until now and I don't see it as a "con" at all. I suspect they are closing because Memolink has chosen to stop licensing their service... LuckyPoints (run by LuckySurf, a.k.a. ValueSurf) also closed a couple of months ago.

Memolink itself, however, is still going strong. I have to tell you that I've very rarely had a problem getting points posted, and when I did have problems, an email to the customer service reps fixed it within about 10 days. I've redeemed from them a few times and they are always prompt to send out the cash rewards (the only ones I've redeemed so far).

It's a shame that PCHPoints is closing as it was another way to earn a few extra rewards... but the main Memolink site is still up and running. I'm sure everyone's experience will vary, but I've had plenty of good experiences with them.
