How do you expect anyone to tell you if it’s a good deal if all you tell us is the cash back and voucher details? In general VM deals have similar acquisition spend, it’s just how they divide it. They may drop the price, increase the cash back, or throw a free item at you. Is it a good deal? Well it’ll be the best deal for that channel at that time. I’d suggest you use Quidco+TCB and whatever new customer offer suits you best.
