Fleurcup EURO 5 off deal Sept 30 - Oct 2

I just received a somewhat cryptic email from Fleurcup, probably because I purchased one from them before: Enter code " -5 " for EURO 5 off of their 14.99 price.

Go to fleurcup.com

ETA: I just bought another one as a back-up, cause I don't have enough cups as it is (insert ironic snort), and it worked.
Including shipping, it came up to $20 and change in US currency, or 14,99 in EUROS.
