My dropshipper charges an additional $1 when multiples of the same item are ordered (shipping for 1 bowl: $5, shipping for 3 bowls: $5 + $1 +$1 = $7, etc.). Is there a way to set a rate for this in Shopify's settings?
I know there are a couple of apps that do this (Advanced Shipping Rules and Better Shipping), but I think they're carrier calculated, which won't work for me, and they just seem so complicated for the one thing I need to do. I charge a flat rate for my products, not weight based. Is there an easy way to just add a shipping rule for additional items?
