I just looked at your main page and found this:
"Hello ! My name is Adam Chen and I leave in Israel ! All my items are free shipping items. You may return any item for a FULL REFUND within 14 days of receipt - all purchases are 100% risk-free. Please do not hesitate to contact me at any time!"
It's mostly fine except that you live in Israel, not leave.
I would say "All items include free shipping/free P&P".
And you need to remove the space before the exclamation marks after "Hello" and "Israel". In fact, there is no need for an exclamation mark at all after "Israel".
