First time poster, so go easy on me =)
Not sure if it's a bug, but Dan's is currently offering up 2 x 4-packs for $30, but when checking out a case (which I think is actually 6 x 4 packs) it calcuates the final cost to be $60, normally $86.99 a case, so a wicked deal.
A few people have pointed this out, but if you add 2 x 4-packs, then add another 4-pack (so 3 in total), the price remains the same. Thanks to those who are a lot smarter than me =)
Worked for me bought a case for $64 not $60. Still a ripper deal!
