There are quantity and shipping discounts for 2 or more sets.
Note: I strongly suggest that you check the feedback of the sellers that you buy your coins from. Was neutral/negative feedback left because the buyer's believed that the seller sent them cleaned, damaged, and/or crappy circulated coins? If the price is too good to be true on eBay, then it usually is too good to be true. I have sold thousands of coins on eBay at a fair price, and I have great positive feedback and many happy customers that are surprised at the quality of the coins that they received. If you want the best, buy from the best.
You are bidding on or buying coins from the picture or very similar to the pictures. Grading is subjective so please look at the pictures and judge for yourself. Even though these coins come from the U S Mint, they are uncirculated and not always perfect. Most if not all of these uncirculated coins contain flaws, nicks, toning, hazing etc. If you want perfect coins then you will need to purchase perfect proof coins with perfect grading.
Contact me with questions and see my great feedback to bid with confidence.
