How far in advance should a refill request be submitted before the purchase can be ready?(with refills available)

For the most part, refills will be done within an hour or two from request. If there are any issues preventing that, an employee will contact you. You are also always welcome to speak with an associate if the refill needs to be completed within the hour. Thank you!

The longest I've waited was 15 minutes.

I usually get mine within 30 minutes of drop off

I always wait for the order to be filled while I'm there and never ends has it been an hour
