You can put at the end of your post “also advertised elsewhere.” Then after leaving the ad up for a day, give to who you want and sort out via private messages. Then just delete your post without explanation to avoid debates/whinging. But, see below.
I’ve given a lot of stuff away over the last few years and I find that the options are:
(1) Facebook mum group. Rich sahms will always be first to comment. They’ll use the item as a spare at their childminders, or put it in their airbnb. But, they’ll turn up on time, be polite, and collect with nice big vehicle.
(2) Facebook mum group where you sneakily via private message choose someone who isn’t one of the usual rich mums, and congratulate yourself on your own charity and cunning. Unfortunately your chosen person will fail to turn up the first few times, make up an increasingly ridiculous series of excuses, then demand you deliver. You’ll then move to the next person who will come, but they’ll look around and start asking for your other stuff that isn’t available and be annoyed you won’t give them whatever they like for free. They hate you and they do not understand the difference between someone who’s ok for money and a council-funded giveaway service.
(3) Drive it to a charity shop, where there will be no parking nearby and you’ll have to carry heavy bag through several streets until you eventually reach the shop, where a suspicious old lady will insist on pawing through the bag in front of you and rejecting half the items at random to show they have standards.
(4) supermarket donation bins for shoes / clothes. Annoyingly, perfectly nice clothes may be turned into rags.
(5) Sell on ebay for £5 plus delivery. This works surprisingly well but ebay demand a lotta info from you.
I usually do charity shop now, or ebay if item is big, but frankly I do also value the quick and easy collection service provided by the rich sahms.
