I've had luck getting an UberXL with a tip, TBH. That was the easiest option for me, and they were ecstatic about the extra cash.
It's a thrift store, they sell on a can and carry basis, they have numbers at the register or will help you load your vehicle or a rental.
They don't actually deliver but follow RamShadow's advise and talk to a cashier about the two people willing to deliver for them
At the register, there are 2 phone numbers available for delivery people known to the store and work for a reasonable fee. That person can be the go between for you and the store. Just ask the cashier.
Call the store or ask at the front desk. The volunteers and staff are helpful. I do not think the store has a delivery service, but have not purchased furniture, which is on the second floor.
