Seems like a really good price? Even on sale at Costco it's $31 for 135 capsules

edit: no coupon for me, though.

on sale it's $7 off, making it $26.99 @ Costco in store (at mine anyway)
the $30.99 is an online sale price @ Costco.com

If you have the coupon, this is a fantastic deal, cheaper than Costco even on sale. Unfortunately no coupon for me.

good price for this mag. I tried a sports research multi vitamin and I liked that so going to give this a go. Thanks

By the way the discount doesn't stack if you up the quantity. price goes up to 20 something.
