Hi,
Do you know of any member protection plugin where it is possible to upload a csv list of coupons for members to be able to sign in.
This is for something like groupon/living social where they give me a voucher list on a csv and then I upload it so that it can be checked before a member gets access?

So basically the person would have already paid in advance and the gateway would be the voucher code.

Any help or pointing in the right direction would be much appreciated.
