Worst case I just get the uhaul packaging specifically for 3 bottles but I was wondering if there are any flatrate boxes from USPS or FedEx plus inflatable bottle protectors that would work. Tia.
Your post is a little hard to follow, but there are definitely 3 bottle Styrofoam shippers you can buy. I'd happily give you some of the ones I have at home (my wife is constantly nagging me about getting rid of all the shipper boxes we have in the garage), but it's likely impractical, if you live in Missouri. Not sure I've answered your question.
If you want fast and likely cheapest, but arguably a little riskier… USPS large flat rate. About $22 If you’re shipping cross country usually the cheapest and fastest option. (Riskier because USPS tends to be slightly more unorganized and rougher with packages) generally not a problem though. I’ve done many many times. Just pack tightly with bubble wrap.
Additionally if you go through UPS or USPS highly recommend going through the pirateship.com website and printing the label yourself.
You can fit 3 750s in a Large Flat Rate without losing sleep over it? I wouldn't even send one in that box
