We will ship up to two standard sized cards (2.5" by 3.5" with roughly 18-24 pt. thickness) for the same low, standard envelope rate. Beyond that, we'll have to bump things up to Ground Advantage ($3.99)...but the good news is....you'll only have to pay this S&H charge once for every forty cards ordered. So, order forty one to eighty cards...pay $7.98 for shipping. Actually, beyond that....we'll figure it out!! The Ground Advantage rate should already be factored in on most (in time, all!) relic cards, thicker cards and the more valuable cards. Also, should note and as most of you already know....the ebay standard envelope shipping option is a nice addition...in theory. It allows sellers the luxury of being able to sell a lot of lower ticket items that otherwise might never sell and most of the time, the process goes very well most of the time (we think) but it is far from 100% reliable.....especially the tracking. WE SHIP EVERYTHING WE SELL (and have for twenty five years on eBay)--within our dispatch time. If problems arise with any transaction, we'll work with our buyers to remedy any situation or issue refunds in a timely manner. If purchasing or making offers on multiple items, please wait for an updated/combined invoice before making payment. Please feel free to take some time to check out all of our listings for items you may be interested in. We realize this can take some time but would prefer to have multiple items per order and not have to pay transaction fees on each and every item we sell. Yeah...we know some of the scans are "off"....if you want a better look at something, let us know and we'll try to accommodate. Also....we have a five BUSINESS day turnaround/dispatch time on all our listings. A lot of the time, we are able to get shipments out way ahead of this schedule. Sometimes, we have other things going on that require us to take the full five BUSINESS days. Please contact us for any additional questions.
