OK, sellers answered my question regarding the postage: after some heavy calculation, the sum is US11.90 for each chip.
Will PM you all with my Paypal address.
Remember to send the money in gift form or the simple Paypal tax may abrade the required money to pay all the chips.
They all go to Chris's address, where he gently will re-post the items to final countries. All hail to Chris for his invaluable service!:bowdown::bowdown::bowdown::bowdown::bowdown:
