At the request of a Alberta lurker, I am passing on some info on reusable canning lids....

Tattler reusable canning lids are now available in Canada through http://www.berkeywaterfiltercanada.com/Tattler-Canning-Lids_c_71.html .
Because the distributor is testing the Canadian market, the largest quantity available through this site right now is 3 dozen. Pricing comparison for regular-sized lids and rings is $27.95 on the U.S. site and $31.95 on the Canadian site. If you spend more than $200 on the Canadian site, shipping is free. This would then save the shipping and duty charges incurred if you order off the U.S. site.
