not entirely sure where this should be posted. but i'm new here, so i apologize in advance if its put in wrong place. i am located in hk , and looking to purchase a few pairs of oakleys , hopefully from the trade section , so i imagine its highly likely american seller, however i would like to know what problems i'm going to encounter in terms of shipping and how difficult the process is . (in case i need to persuade seller) i am perfectly willing to pay the cost, just wondering if there are hidden charges or customs issues and whether theres any other things i need to be aware of . i also not entirely up to speed on how transactions are handled, i see the word paypal here and there. but would like to know what that actually consists of. does simply having a paypal account suffice? ( i not even sure if my accoutn is still active and quite frankly i rarely purchase anything online through other means than credit card). thank you in advance. i simply want to be prepared when the big moment comes.
