kohls coupons on ebay

Does anyone know of the method that is used to get these coupons,

I assume its some bot that signs up on the kohls website

I used to sell these.. But I do not think that it is worth it anymore. You have to change ip plus a new email. The price is only $4 for 20 of them which is awful and your eBay acct will be flagged in a week so you need to make multiple paypals and ebays...

Trust me not worth the effort anymore I sold these for 1 year but now it is over saturated and dead..there is always something new
