This is one of these posts where I'd really like to hear only from sellers with direct experience of this situation.
I don't need to hear what "should" happen; I can see that for myself. It's what actually happens, which seems to be quite different, which concerns me.
I have issued 10% off coupons to three of my best buyers. One has been able to use the coupon without difficulty. He only buys individual items, and seems to be able to input the code and secure the discount.
However, the other two both buy multiple items on at the same time from different listings, so they have the added step of asking for an invoice with combined postage.
BOTH of these buyers are adamant that there is no space for them to input the discount code, either when they request the combined invoice, or when they go to pay after receiving that invoice. Obviously, I can refund the 10%, but the process is supposed to work, is it not?
So, my question is; where and when does the buyer enter the code to secure the discount when purchasing multiple items? Again, I'm looking for people with experience, not those who have just looked at the t's and c's, because it definitely is not working as it should. Also it's impossible to replicate without a 10% coupon of my own, so I've had to rely on what my buyers are saying, although both say exactly the same thing.
Any guidance gratefully received. Thank you.
