Snap-On doesnt publish them online and they're often regional though, oddly, you'll often stumble onto the universal hot tool sales on their website if you browse around enough. Why they dont publish at least those in their own section i have no idea. Then again Snap-On's site is terrible and should of been upgraded to a more modern UI a long time ago.
Cornwell and MAC are the only two that publish an online flyer but Cornwell doesnt sell online and MAC doesnt discount their online store. Six in one half a dozen in the other.
