There are lots of great sellers on CardShark - prompt and true to their word. Occasionally, a buyer may come across a seller who does not meet expectations. Providing other CardShark members with a quality-based ranking of a seller allows buyers to make informed decisions. "Leave feedback for sellers" on your My Account page is the place to rank the seller and provide comments (1 being the worst and 5 meaning the seller went above and beyond expectations).

If a buyer purchases cards from you, the CardShark system sends a confirmation email to you. The email indicates the date by which you must confirm the order. To confirm the order, log into CardShark, go to "My Account" and select "Confirm Order." You can review the items before you confirm the order. Click "Confirm" to view the shipping address and print the invoice or MTGO contact information. Buyers are automatically informed that you have confirmed the transaction.

"Manage Inventory" is a great place for sellers to effectively manage and view all items they are selling. The seller has three options: individual cards by name, cards within a set, and the Advanced Inventory Management tool which allows you to view your cards by set in a long list format. Any option will allow the seller to make changes based on quantity, price, condition, etc or to delete cards.

"View Payments Pending" allows the seller to find out when the expected payment date is for a particular transaction. Each pending transaction is cleared when payment is received. To review each pending transaction, click on the transaction ID. Note that orders pending e-check payment are not listed here until the payment clears.

Another method to better manage your transactions is to view a history of all past transactions through "View Payment History." You can also review the order details by clicking on the transaction ID number.

Please be sure to review our How to Buy section, where many common questions are addressed.

Find cards to buy using our Magic search engine. The easiest way is to Search by card name in the left corner of our home page.

You can also browse cards by set and search specifically for foils rares or foreign (non-English language).

Add cards to shopping cart by selecting Add to Cart next to the desired card. Remember that your shopping cart only stays active for 90 minutes after your last access of our site.

Leave feedback after receiving your card(s). Go to the Your Account page and "Leave feedback for seller." It may help other CardShark members make better decisions when purchasing their cards.

Once you have found the card(s) of interest, place it in your shopping cart by clicking on "add to cart" immediately to the right of the listed card. If you wish to continue hunting for cards, select, "continue shopping."

It is a good idea to fully complete your Paypal account prior to conducting a transaction. If, for some reason, you do not complete your account registration with Paypal, CardShark reserves the right to cancel the transaction and free up the inventory for others. If you need to interrupt your card-buying process to update PayPal information, you have 30 minutes before the CardShark system frees the inventory for others.

You can pay using only a credit card. These transactions are still processed by PayPal, but you don't have to register for an account to pay for your cards. Simply click on the "If you do not currently have a PayPal account" button and proceed on PayPal's secure server with your credit card payment.

Buyers often ask CardShark why they should buy postal insurance. CardShark offers this option so that both parties - buyer and seller - can recoup their losses if your order is lost in the mail. If you choose not to purchase insurance when a seller offers it, please realize you are taking responsibility in case of loss. Note that this option is not offered to buyers outside the United States.
