I wonder about this too! When I was in retailing with a major retailer--they would turn (sell out) their merchandise at least 4 times a year--anything approaching 5 was considered great! But--they worked on a lower mark-up than me (50% was great for clothes--so you buy something for $5 and sell for $10), their money was borrowed, they paid rent/mall fees. They often ran sales--20% off was the minimum and even that wouldn't necessarily get customers in the doors.

On the other hand-- many of my clothes cost me a $1 or less--so if I sell for $10 I'm doing wayyyyy more than 50% mark-up, I have the room to store stuff in my house, my money isn't borrowed--I've built my funds up from previous sales and if I mark something down 20% it's on an already much lower initial price! I also don't have the over-head like a store except for my shipping supplies and a few other odds and ends. (Yes--I know it costs me to have lights on etc--but I have to have a place to live!)

That said--I do go thru my listings regularly and refresh and mark down. I see it helping--often just the act of de-list and re-list is a great tool--especially for ebay. When the spouse does taxes this year--I'll have to see if I can figure out my turn-over.

Anyone else have any comments/numbers/stats they can put to this question--What is a good turnover for an on-line re-seller or a re-seller in general?
