Soap.com has Vaska (and so much more)
I'd never heard of this site so incase anyone else hadn't I thought I would post it.
Soap.com carries so many brands.
I noticed they have Vaska (cheaper than Drugstore.com) and free shipping over $25. They carry the larger 64 load bottle too.
They also have Method (including new scent Lavender Cedar).
Wish they shipped to Canada but no go ...
