Just that really. I keep being added to a local selling group and my timeline is full of people selling crap used goods for not much less than you can find them on Amazon/the high street and definitely for more than you'd pay at a car boot sale/ NCT sale/charity shop...
Today's gem is someone looking for a new purse and a reply offering to sell a purse with tags bought for £16.99 in TK Maxx for £14. Original poster has asked if she can collect... Unless you wanted that particular purse, or another specific item, wouldn't you just go to a shop and buy a new purse?!
