What the hell is it with everyone suddenly coming onto this period tracking app, and posting their personal promo codes for this app Mercari??? Claiming that you'll get free stuff, which by the way is NOT true. It's an app to buy and sell stuff, none of which is free, and 90% of the stuff on there does require shipping fees. My point is, STOP POSTING YOUR MERCARI PROMO CODES ITS SOLICITATION AND ITS NOT ALLOWED ON THIS APP!!!!!!!!! Nobody's interested.
