Let someone who knows what they’re doing run the selling of shirts.
Have a proper dedicated retail site, like mine , or use eBay. The reach of eBay is global, posts on here and FB/email is probably less than 10k. The antiquated system of emailing in an offer without any real sight of others bidding activity is so frustrating too. With ten minutes to go, I have no idea of whether to bid £20 or £200 on some items. Needs completely rethinking.
