I am manager (of 7years) of our local chain charity shop I would just like to say a couple of things, firstly i agree that some charity shops have gone mad with their pricing, if i get something nice ie radley bag last month i researched it on ebay priced similar £50 and sold it in a week, had it not sold in 2 wks or so i would have reduced by £5 or £10 then eventually sent it to our company ebay seller. i have 1 year old and i buy most of her toys and clothes from charity shops inc mine(not priced by me) we have rules that state all items must go on shop floor for 24 hrs and priced by another person before being purchased with 20% staff discount.
we do have set price guides to stick to if item not worth min on guide chuck/rag/recycle it but at our disgression to mark up(I often research on ebay and internet and aim for 33% of new price).
yes we do get alot of rubbish the usual: incomplete toy/games, broken kitchenalia ripped chewed books etc but among the worst things I have found are USED loo brushes, USED loo seats,USED vibrators, unwashed stained underwear, burnt frying pans, broken glasses, tupperware with contents in and so on. I hate car boot season cos on sat afternoon and monday morning (usually left on sunday afternoon so is vandalised by monday) we are inundated with unsold car boot crap, if you didnt sell it at car boot what makes you think we will sell it!!. we do earn money for rag clothing, shoes and handbags and unsaleable books but the loo brushes etc have to go in the bin at a cost to us!!
also charity shops that have leases do pay rates(poss reduced), rent, gas, electric, insurance, and all the other normal business stuff I am paid (not very well) but i am reponsible for h and s, risk ass, stock rotation, stock processing, takings to bank, managing vols and general company guidelines our shop is profitable for the charity (about 40% of our sales is profit)
not only are charity shops for bargains but we also have a great team of vols that contribute up to 100 hours a week mostly retired, unemployed and special needs that are looking for someting to do, gain work experience, trainees for nvqs etc i have a couple of vols that have been recomended to volunteering for help with confidence and depression and it has helped them
