Source for discount jiffy pellets

Does anyone have a low cost source for Jiffy 30 mm pellets? I prefer to not pay shipping but I cannot find a good low cost alternative. It seems cheaper to just keep buying the trays and prefilled inserts from WalMart but I have tons of them that I have kept through the years.

The most frustrating part is that everyone sells the preloaded trays (preloaded with 30 mm) and they sell the 45 mmm refills!! What is wrong with the people ordering?

Shoot me a reply if you have a source. The best I have found so far is $.15 each and I have to pay shipping.

Hello mrsmith,
I have Jiffy #7, which are about 1.5" in diameter. I think that is about the right size, my brain does not work in 'metric'. It is possible we can help you, you did not say how many you needed. You can e-mail us at wan.pointloma@yahoo.com if you wish.
