problem is what markets online there isnt any real choices here 

vinted...its full of bargain hunters and grave robbers you ask a fiver they,ll offer you £3 and i,ve seen stuff on there uploaded more than 3+ months ... plus its flooded with ex e bayers.

facebook...you get plenty of clicks but very few buyers plus its full of scammers and timewasters who are the bane of my life.

ebid/ gumtree ...i,ve seen more life in carlton cemetary.

etsy ..expensive to set up on there plus its restrictive as to what you can sell

amazon... PASS

as for the others i dont think they attract as much custom as e bay did 

e bay knows its got you by the wotsits selling wise and seems to think itself unsinkable so it can do what it likes  to screw as much out of its sellers as it can.

so it looks like 3 choices stay as a p/s and go a week plus without any sales grin and bear it

bite the weenie and go to a B/S  possibly the same as i,ve just said or maybe a couple of sales a week but pay 36p and a fvf for the privalage of doing so... or  just give up the ghost.
