I'm trying to find the cheapest source for German-made Persil Megaperls. I'm located in the US. I've seen previous recommendations for Better Products Online, as well as a Canadian store (Vacuum Specialists) that does free shipping to the US.

The best price I've found is ~$37 shipped for a 3.33kg box of Megaperls (when purchased as a 2-pack from Vacuum Specialists). While $37 is the cheapest I've found, it's still quite expensive. Does anyone know of a better source for Persil Megaperls? Thanks!
