I personally refuse to order from vendors who don't use vac seals for substances that dogs can smell, but feel free to order shit that has absolutely no measures taken against dog hitting on it if you think it isn't helpful to vac seal. Funny thing is that all the literature I can find on drug smuggling organizations lists "vacuum seal shipments" as something that the most sophisticated smuggling operations do, with less sophisticated operations taking no countermeasures or ineffective measures like cover scents. edit: maybe I should have read your full post instead of just the first sentence before I made a reply to it
