I know, 10% doesn't seem like a big deal, but it really is. Especially for wholesale goods. It you are reselling the trims by the yard, not only are your margins 50-80% or more on our products, but add another 10% off is like an additional 20% in margin! So for a $500 order, easily done in business, it's the cherry on top.
Speaking of cherry on top, we just decreased the flat rate shipping to a mere $7.50 from the standard $8.50 we have charged for years on all but international orders. So maybe the 10% off is like the hot fudge and the flat rate shipping is the cherry on top.
Oh, and no need to remember to add any discount or check a box, the discounts and shipping rates are automatic. Now we're talking whipped cream.
