Best way to ship on ebay?

-Whats the cheapest way to ship baseball cards on eBay and how much will it cost?For larger amounts of cards like complete sets (which can be heavy thus costing quite a bit) priority flat rate boxes are an excellent economical option. The largest flat rate box can hold up to 5 standard sets for only $14.95. For individual cards a reinforced bubble mailer first class is the cheapest way to go.
Use 1st class mail and secure your cards in thin cardboard to

avoid bending & damage
