Do you garantee your codes? Asking because the last purchase of 35 codes at one time from another Listia Seller was troublesome! Ten of the codes had already been activated! I think the seller had already used or sold the 10 and got them mixed up.
As far as I know all are good, but I will send an extra 10 codes just in case a few are bad. This happens sometime even when you open a fresh bottle. Some of the codes are bad from the factory, no many but some.
