This makes me want to join some LTC trackers!!

That's interesting . . . with so many people who are scent-sensitive, I'm surprised that postal workers aren't objecting to have to handle scented mail. Even though it's probably pretty subtle, I have been in offices that post signs requesting clients/visitors wear no fragrance (perfume, soap, lotions, hair products, etc) of any kind, out of respect for those who have sensitivity.

I wish they would focus more on quality of service instead of wasting time and money to try to grab the interest of stamp collectors :'(

But they are cool, and I might even buy a sheet. If people were really collecting wouldn't the PO be doing better financially with people buying stamps and never using them though? I mean I used to collect (still have the ones I collected) and still do from time to time so it kind of confuses me.

You don't need to join a tracker to "scratch and sniff"
