@sam9876I offer 3 shipping services. First Class, Priority, and Express. Not to mention shipping for international countries (also with 3 services). Are you saying you would just put free shipping on all of those? I'm not just asking this question for First Class domestic shipping. You'd be losing a ton of money. Or if you raise your prices to cover international shipping costs, no one within the US would pay those outrageous prices.
@pjcdn2005Yes I have a shipping rule testing out the 1 dollar off for additional items in that exact section (where it gives the green text advertising the discount in the shipping section). At the same time I also have shipping discounts shown in each individual listing (which shows the exact shipping price for the first item, and price for each additional). For instance, I'll have a listing that has a 1 dollar off each additional item for First Class shipping in the listing that also points to that flat rate combined shipping rule. I've been noticing if one overrides the other, or do they give simultaneous discounts. So far I haven't noticed any purchases that received both discounts... I believe the buyer got one or the other. I guess I have to play around with them to figure out what works.
Flat shipping rule allows the discount to span thru different listings. But it doesn't help if I want to create a larger discount if the buyer chooses Priority Mail rather than the default First Class Mail. I.e. 1 dollar off if you choose First Class Mail, But 3 dollars off if you choose Priority Mail.
