I missed your original question, sorry!
I've gone back & forth about wholesaling. Here's my current position (subject to change).
For an individual who comes to my shows (where I've raised prices by 25% to cover show expenses, etc.) I usually give a 10% discount to any purchase over $100. I don't *offer* it as an incentive, I just knock it off when I'm writing up the receipt. Kind of a nice little treat to someone who's willing to buy that much.
I won't do large scale wholesaling at shows anymore. I had a minor ordeal with buyers from one store at Tucson and it really caused me to think all of this over. I understand their wanting a "break" but I need to cover my financial posterior, too. I'm about to put this new policy in effect in March, when I revamp my Ebay store and website. From April on, I'll give a wholesale discount of 30% to anyone willing to order $300 or more of my regular bead styles. That won't include auctions or other odds & ends, just my regular stock. I'll be asking for a 50% deposit, make the order, then get paid the balance prior to shipping. I'm willing to do exchanges on any beads that aren't "acceptable" but no refunds. I am NOT WalMart! Also, the prices on my website (which will go up a bit in April, too) are about as close to rock-bottom as I can get. There's a small pad of profit built in, according to my formula, but not buckets o'cash. For me, I feel it's fair because my costs are so darned low. Especially since they lowered the prices for store items. With the inclusion of my website, my ebay store and listing fees, my monthly "internet overhead" is about $25. That doesn't include Paypal and Ebay FVF, but together that's about 6% of my price. Helluva lot cheaper than a $300 show, plus gas, plus hotel. So, I pass MY savings on to my buyers (cuz I loooooove my buyers!)
All of that said, giving much more of a discount would cut my throat. However, there's a nice security in knowing that I can get and additional $300 if I knuckle down and PRODUCE for a few days. $300 of my average beads comes out to about 15-20 beads.....two days' work at most. And a sure thing cash-wise at the end. I can live with that! I still make a teeny bit of profit and I KNOW the money will be there, so I figure it's worth it.
That's it, in a long-winded nutshell.
