Purevapes really depends on how busy they are. I've had morning orders ship the same day, and I've them take a couple days.
Eliquidmart.com - I ordered Friday, got a 'label created' entry on the shipping info Monday, wasn't 'accepted for shipping til Tuesday, so I guess they don't do weekends. That'll be a whole week between ordering and receiving. Past orders from them made in the morning have gone out the next day or day after.
Ecigexpress has shipped same-day for my morning orders, but usually by next day.
WizardLabs often took a couple days to ship when I used them for nic and PG/VG, but a couple orders of flavoring only were at the post office the next day.
Highdesertvapes depends on how busy they are and whether there's a sale. Once I was in desperate need and let them know - they got a 3pm order out the same day. Awesome!
Desertvapes has always been same-day shipping for morning orders, next day for afternoon orders (I've gotten only hardware there).
can't remember who else I've ordered from lately...
but I remember ordering stuff as a kid that took '6 to 8 weeks' for delivery. It was always a surprise when it finally arrived. Anyone who missed out on that nostalgia can experience it now by ordering from Fasttech. lol!
