If I bought a couch in store, would I have to pick it up that day or could I pick it up within the next few days when I had a bigger truck available?

Talk to the on duty manager.

I had my washer and dryer delivered. Sorry, I don't know more. I've seen people rent vehicles from places like Home Depot to make deliveries. They advertised $19 for the first 75 minutes. Don't know if that suggestion helps though.

I'm sure if you explained to them that you cant get a truck for a couple of days they would understand just call and ask

I bought a matress and washer, they delivered. I dont know about pick up options.

I tried to buy a mattress and have them hold until the next day but the associate I spoke to said no.

Check with management
