I live near Chicago and got a $5 shipping estimate for the same sized order.
When I was checking out, the actual shipping charge was $9.

Only 4 bucks more, but a
considerable % increase.
I decided to call them and I'm glad I did. I talked to Bri and she could not have been nicer. Bri told me the reason it jumped so much was because I selected Residential Delivery at checkout. (UPS Charges more for that...I guess)
I went back to my computer and did NOT select Residential Delivery, put in a commercial address and the shipping fee dropped back to $5.
I'm not sure if this will work if using PayPal.
They ship from around the St. Louis area and the bottles I selected were delivered to a convenient commercial address (for me) the very next day.
I'll be back!
