I am sure if you read the fine print then you may understand the 'sales model' built around a voucher system. Essentially you see a product at a great price - then pay for it (at the agreed price) then they send you a voucher which I now understand you have to pay for (on top of what you already paid).
If fail to buy the voucher you potentially lose your money. Again for low cost items - the so called 'bargain' is no longer as good as it seemed.

I don't think one could establish the voucher price (even if you knew you'd receive one) befor eyou pay for the initial goods - could be wrong - I'll just avoid in future.

Customer service very poor.
