Here, Grolsch is $8.15 a four-pack, $2.04/bottle. 34 would be $69.28.
AHS amber bottles are $12.98/12, $2.49/bottle, free shipping if added to anything else.
Best eBay price I've seen is $1.61/bottle (after shipping). [I'm amazed how many sell after shipping much more than $2.04/bottle.]
$45 is a good deal.
