If you wish to sell via the deckbox site, the rules require you to have a sellers account. Otherwise it is against the rules to try and sell outside of the site while using the forums as advertisement.
Just in case I am misunderstanding the question, if you are just asking for advise then I can try to help. Depending on collection size, 10% may not be enough of a discount for cards. When trying to move a large volume of cards fast, you will tend to have to lose out on value just to move it quickly. A LGS will probably only offer 50%, maybe less depending what they see in the collection that they actually want. Best way to get the most value is to sell it piece by piece.
