Suggestions;
1. bad idea to type in all capitals -- hurts the eyes, hard to read, called "screaming." Needn't be bold, too.

2. I don't see where you give the condition of the chip.

3. $1.000 for shipping seems a mistake. Also, further down it says "insurance not offered." I'd say "buyer pays $3.00 [or whatever] postage-insurance."

4. I'm confused about the number known -- you say 8 to 15 and 8 to 10.

Best,
Robert
