Because the answer is no.
If you pay by e-check thru pal.
Most of the items listed here are low dollar and lots questions that do not pertain to item or a great time waster I have for these kind wasting.
Nice transistors.
Who have a bank account in USA. Before you leave bad feed back.
I do not combine shipping and handling for separate listings. 4 pieces of Motorola MRF8004 rf transistors. I only ship thru the USA postal service this works best for me and feel over all be everybody.
This will save all of us time and money make for a smooth experience on.
