SHIPPING

Since the pandemic our company has downsized tremendously.
Because of this we are only open, and only ship, on Mondays & Thursdays
To compensate, depending on when you place your order,
we may upgrade your shipping to Priority Mail
So, though your delivery time may say 5 days
It probably will be much shorter.

Example: If you order on a Tuesday or Friday, your shipping will probably be upgraded.
If you order on a Sunday or Wednesday, probably not.
