To keep costs reasonable, orders up to 20 cards and/or $30 or so may ship as reinforced flats. (If you want package rate postage with tracking on smaller purchases, please select the 3.99 option at checkout.)
If there is ever any issue with your order, please contact me directly rather than using eBay's automated claim system. Also, keep in mind the pandemic-related postal delays and labor shortages have pushed many delivery times well beyond eBay's "estimates." While some orders are still arriving in 4-6 days, many are taking as long as 4-6 weeks. Rest assured, once your item has been marked as shipped, it is on its way, even if it is a smaller untracked order. I did not lose a single shipment in 2020 despite some very long delays; it has been a frustrating year, but with a bit of patience and communication, everything has worked out just fine...
