We have our product in 4 colors, all on same page (variation). Our promo code is one per customer which includes all 4 colors.
If you buy one color you cannot buy another color. All 4 colors have there separate listing on Amzreview...we do mention in those listing too that you can only buy one color per product but most reviewers are not reading I guess and still apply for all colors.
If they do get approved only one code works and then they complain to customer support about us giving out non-working codes. Is there any way to fix this situation ?
