Holiday Weekend's next then (bourbon BA version)... Probably only twice as expensive as well

It weighs on my conscience this... My regular online beershop (I usually do a ~2-300€ order every month) had two sets of Prairie for sale back in February... Both sets had one very limited and very expensive Prairie beer that I wanted, and one I already had... I asked the sellers whether they could fix me a set with both rare beers... Sure, they said, they'd get back to me with the price cause it'd be more expensive than the sets online... I had just finished doing an order that day, and lo and behold they sent me both Prairie beers in that order, before I had paid...
I sent them a mail upon receiving the beers, thanking them and asking them for the price so I could pay them... Long story short: I asked them again four times in the three subsequent months... They always thanked me for reminding them, but never sent me a price... I've stopped asking them... It's "only" 40€ giveth or taketh, but it still doesn't sit right with me...
So I did the right thing and placed an order of ridiculously expensive beers last Friday, stuff I'd normally not buy, to make up for it... Win/ win?.. I dunno...
Drinking away the feeling of guilt...
