Bob,
There is a very simple way to send Mail from you House. P/U a Gram scale weigh the completed envelope,can convert immediately grams to ounces,on the net,or print out a conversation sheet. Use the Post Office credit card system. I use Pay Pal instead. Print Your ticket,tape to package,up to 12 ounces,or use priority mail,$5.05,including free confirmation,any weight. Note: on smaller items,you will have to use stamps,but will get the lower rate,of .86 cents,if appliable to the weight. Drop in your Mail Box.no traveling. If to big,leave a note for mail Man,please blow horn,& hand him the Package,or call for a p/U. If you envelope weighs under 28.35 grams,it only cost a single .46 cent stamp. Basically eliminating the attendant. Never get a come back..
