you can do that...the only difference with flat rate,is the amount stays the same no matter the weight.In many cases,if you put "perishable" or even "live plants" on the box,it *may* get handled a bit faster.
I work for the USPS,and in the larger plants sorting is done by machine,but in many smaller ones,the packages are sorted by humans.Most people who work here want your things to arrive ok,and will do their best.
in most cases,a small flat rate box will cost less to ship then a larger package.I'm not sure why you wouldn't use a flat rate box,they are handled the same.
MTS? no,I just need one more tank...
