I just got an email from Threadless saying that I could use coupon code MAY30 for 30% off my $20+ order, but then I tried to use it and it didn’t work. I was, however, buying only shirts in the $9.95 section, so it’s kind of hard to complain about spending $10 instead of $7, when my picks were originally $24 (especially when they’re my kids’ favorite shirts).
I’m still a little miffed that the email says “some exclusions apply” but then I couldn’t figure out the exclusions. Perhaps, say, that you can’t use the code on items already on sale? No matter; maybe you can use it on something. [Edited to add: Apparently it only works on items ending in .00.]
