I just did a comparison on selling at $3.00 plus $1.20 postage, versus selling for $4.20 with free postage. Fees wise it only took 10cents from my bottom line, but I don't think the $4.20 sell price would appeal to many. Perhaps as stated, put the postage at $1.20 and keep offering to combine it. I can fit 4-5 packets in one envelope and still keep the postage at $1.20. It might go up to $1.80 for multiples of larger beads, but that is still a discount if they have ordered more than one packet.

I think that if you have to incorporate the free postage into your price, people will see it and the smart ones will realise that they are actually paying more than if they were able to pay postage but combine it for multiple items.

Happy selling everyone!
