Query: Product Description...Omits a critical detail

I ordered this item based mostly upon the positive reviews... look, this Pellet Revolver really may be the "bee knees", but... I wouldn't know cuz... IT DOESN'T COME WITH CO2 CARTRIDGES!!! No where in the Product Decsription does this get mentioned... I wanted to use this thing right away and for some reason it takes ANOTHER WHOLE WEEK to get the CO2's delivered via Amazon... C'mon Crosman, get your act together and ensure people know what they're buying! Ya, I'm STILL waiting on the #@&% CO2's to be delivered, so... I'm not a happy camper... (BTW... i purchased the ammo at WalMart, but that also does NOT come with the gun...)
