Multiple Offer Used at Once

So this is an interesting one.

at 00:03, I wanted to update my shop newsletter and create a coupon one..

I created a coupon and added to the newsletter.

all was good, until I used my partners account to see how it looked from a buyers point of view.

I’m also currently in eBay’s coupon which has a 20% off, which is already amazing. So I got her to add to items of mine to her bag, copied my coupon which gave the discount. 
When going into the basket my personal coupon discount was added, but then I noticed eBay’s coupon was also added, so 2 coupons were allowed at the same time giving a total of 30% discount.
I didn’t think multiple coupons were allowed at the same time???

is this a new feature??

I know when you have a sale and there’s a coupon that can be used.

I’ve though is was best to postpone my shop newsletter just in case.

has anyone else noticed this?

thank you

So was one coupon yours and one Ebay's?  That would make a difference as you cover one and they cover the other.

Do the T&Cs say only one can be used?  If not it appears from your experiment that they can.

So one was eBay’s which we both contribute, but I had a 10% coupon as well, it was letting both coupons be used. 
I’m sure you couldn’t used them in conjunction with any other offer other than sales. I swiftly cancelled my coupon until the eBay one ended.
