I personally like taking the spray samples I get from places like Beauty Encounter and Sephora. Both I get online. Plus - these can do the whole quart bag, no more than 3 oz thing quite well.
I'm on travel right now and the 3 spray samples I have with me:
- Guerlain Insolence - Sephora
- Neil Morris Storm - NeilMorris.som
- Ormonde Jayne Osmanthus - Ormonde Jayne.com
If you want to decant your own stuff - there are suppliers who will send you 1.5 mL spray bottles. I tend to use the spray samples I have so other basenoters may have better info on how well these work.
Another though is to do what Quarry did and focus on going to local perfumeries rather than packing stuff. She'll have lots more information on that than I will since she's been there recently.
Hope this helps.
