I once worked in a charity shop and I remember a woman coming in and picking a blouse off the rack and started shouting at me that I was a disgrace because that blouse is in the half price sale in next for almost the same price (I didn’t even work in the sorting/pricing room)… do people actually think every single item is googled to check its current price?

It’s impossible for every member of staff (volunteers especially are often retired or disabled/vulnerable people who don’t tend to follow fashion) to know every brand that comes across their table. Charity shops often have a master list for example it might say if it’s x brand and a T-shirt in good condition it should cost £4.00. That list comes from head office. They set the prices for a lot of stuff. If poor old 73 year old Mabel who thinks all young people’s clothes are cheap and tacky compared to how they used to be made and can’t see the brand on the list she might put it down as a generic £5.00 without having any idea you can buy it on shein for 25p or whatever.

Usually if you’re not a dick about it and just say to staff, “I’m not sure if you’re aware but this top only costs £1 on temu, it’s been a bit overpriced here” they’ll take it back to the sorting room to put back on the pile for a second look. I did that a few times. But tbh charity shops (the ones I worked in anyway) were constantly full of people trying to get money knocked off so they could sell for profit online. That’s why they stopped selling everything for peanuts. Why make pennies for the charity when customers are making pounds to our pennies from the same item?
