Reportedly, there is a $1.50 OYNO WYB 2 Containers and a $1.50/2 Q for Ziploc Containers. The safeway site price in my area is (not on sale) $3.99ea (8oz containers are 6-ct; cts vary), so....

$3.99x2 = $7.98
-$1.50 WYB 2
-$1.50/2 Q
-------------------
$4.98 for 12
~$.41ea

This is not a bad deal for containers if you're running low like me, but if they go on sale...lookout! WOOT. They often go on sale 2/$6 or 2/$5 in my area.
