I have actually been a longtime member of Couponcabin and have used it to save at least a couple of hundred dollars over two years, which is nothing to be scoffed at. However, they have a very faulty technical system and that is coupled with a less than optimal customer service team.
1) Couponcabin has a rule about not allowing members of a household to avail of the "members only" offers. Which is a confusing rule to begin with because it's not like members of a household would confer with each other every time they are making a purchase. Especially once you install the couponcabin sidekick app which reminds you to check their offerings before you shop.
2) Their system of identifying so-called violators of their terms is by using IP addresses. This is EXTREMELY problematic given how many people might be using the website at coffeeshops or other public places. Or, in my case, using a building wifi. How IP can be a reliable way of determining household is beyond me.
3) I was recently blocked from Couponcabin and had my account permanently closed. Their reason was that multiple members of the same household availed of their special offers. At the same time that my account was shut, they also shut the account of a friend in my building. As I explained to Couponcabin, us using the same wifi is not the same as us living in the same household. That is an absurd claim. They then emailed both of us saying that we had opened multiple other accounts using the same IP address. Which, of course, we hadn't. Shouldn't the existence of a number of accounts at the same IP suggest that many people are in fact using it and therefore it is probably a public wifi?
4) While couponcabin paid me most of my pending balance, they refused to extend the same courtesy to my friend from the building. So the friend whom I referred to Couponcabin is now out a bunch of money that he spent upon my referral. This is grossly unfair to both him and me. I do not understand why they would apply the rules differentially like this.
We have exchanged many back and forths with the Couponcabin customer service team, and frankly, they only reply with rather curt and rude scripted emails. They do not respond to specific questions and explanations.
I would not say that you shouldn't use Couponcabin, but if you do, be extremely careful. Otherwise you might end up spending a lot of money thinking you are getting a good deal and end up having spent more than you might have otherwise. Simply because Couponcabin decides to rescind its coupon to you.
I also expect that if at all they reply to this complaint, it will be in the standard "we have very few rules" script that they have already used in response to other similar reviews on Sitejabber. I find this kind of customer service, without regard to longterm users, to be rather shocking in today's day and age of excellent customer service.
I'd also like to add, as a final point, that it is rather insulting on the part of Couponcabin to assume that some people might have the time and energy in their lives to set up endless Couponcabin accounts just to "violate their terms and condition". The simpler answer must be that their identification system is so patently faulty.
CouponCabin has very few rules and the rules we do have are in place to make sure we can pay as much cash back as possible; it’s how we’re able to offer such great deals that you can’t find anywhere else. In addition, we make sure these few rules are prominently highlighted across the site when using our cash back program. That said, when accounts are identified as trying to get around these rules, we have no choice but to close those accounts.
