An established business (on this forum) isn't always expected to use escrow but is generally accepting towards it. As a new member, only accepting escrow for an order of 100 pieces + is an outrageous and unrealistic demand.
Perhaps consider accepting a forum escrow for all purchases (at least for the start) until then, buyers beware.
As escrow take huge margin so there is no worth using it for low pcs i think you may understand
Transaction Amount (Merchandise + Shipping)
Standard
Concierge
Express Deposit Fee
$0-$5,000
3.25% ($10.00 minimum)
6.5% ($100.00 minimum)
Standard or Concierge fee + 3.05%
We have to cover shipping also and margins are very low you can now understand.
