As always, when buying anything on the web, make sure you know what you are agreeing to.
I have just realised that I have been paying out £10 per month and getting nothing back for it. But worse still I do not remember giving my card details to the company concerned. The entry on my statement was for SHOPPERDISCOUNTS.C, so I Googled it and found that this company appears very well documented on such sites as MoneySavingExpert, ThisIsMoney and The Mirror  amongst many others.
Now, I'm actually more annoyed with myself than with the company. I'm usually very good at checking my statements, but obviously not as good as I thought I was. It's been a wake-up call for me.
Thankfully there was a telephone number 0808 234 1539 and an e-mail address email@example.com.
Anyway, the good news. I gave them a call and they very quickly agreed to cancel the account and refund the fees. In fact the girl seemed really knowledgeable and expert in knowing how to handle the call, the cancellation and the refund. One suspects she's had lots of practice.
The company is 'Shopper Discounts and Rewards'. It has partnerships with many well known high street names. When you buy an item over the internet from one of these you are asked if you want to receive £10 off of your next purchase. If you tick the box and put your details in you will be charged a £10 monthly membership fee that basically gives you access to a discount site. I must have ticked the box, but I do not remember putting my card details in. A look at the comments from the links above will indicate there are many people who agree with this.
Having been informed that I must have had a welcome e-mail and monthly updates I checked and found that I had. But, although I don't always delete them, I always ignore this type of e-mail as spam so would not have opened it.
I am not saying that there are no discounts, I didn't check, it may be just what some people want. What I am saying is that the method of getting me (and many others it seems) to join without being properly informed that I would be charged £10 monthly is wrong.
Some people on the websites and forums above complained that they'd been paying this for one or even two years without noticing!
My message? Please check your bank and credit card statements and if you see an entry for this (or anything else you don't recognise) then check and do something about it! And if you see an offer to save £10 off your next purchase when buying over the Internet, be very careful indeed!
