This is what happened where I work. We use to have unlimited time frame for returns but now it is 90 days, after which a store credit is issued for the lowest selling price.
I don't see a problem with banning customers who return a lot especially if there is reason to suspect something fishy. I'll never forget this lady who was returning several handbags and she pulled out a huge stack of receipts. Anyway during the transaction LP intervenes and states that they've been investigating her purchase history and found that she had a 90% return rate Anyway she was eventually caught for tag switching.
What is "tag switching"?
I'm missing something here, I understand it as: she returns all these bags and has receipts for all of them...but switches the tags so the wrong bag matches a wrong receipt????
I must really need some caffeine....
