Prices of nices in charity shops?

It seems to me that some charity shops are overpricing some of the stuff thy have on sale. i can buy stuff brand new for less than they are asking on the tag. yes i appreciate tht they need to get the best price tht they can, but surely by lowering the prices to a more realistic level the shop would turn the nices over faster and therefore make more money for the charity concerned. anyone else agree?this relates to shops in the uk, not sure about anywhere else.

When charity shpos first started all the good they sold were a bargain, but they became to popular and the result is the ridiculous prices they now charge. but orginally they started out as small shops run by local volunteers. but have no been swallowed up by some form of corperate marketing and most have large exspensive offices paying stupid wage to blokeagers to run the bloody things. i cannot be sure but i believe some of the blokeagers are on upwards of £100000per year with all the perks thrown in as well the sooner the shops get back to grass roots the better it will be for all i am all for raising money for charity but let the charity be run by volunteers. in some charity shops the money raised for charity is less than the wages paid out this is wrong. i for one say get back to the old days
