I believe this price has been live since Friday and it appears it will end tomorrow (Monday) 4/27 around 11AM EST unless they pull the listing beforehand

As far as I can tell this is the best price per Troy ounce for silver that doesn’t require you buy 100 or more units and includes free shipping, no tax (for most), low purchase quantity and the ability to use a credit card.

Current spot price appears to be ~ $ 15.74 which makes this exactly $ 1.25/Troy ounce over spot.

Remember these are rounds as in they are not "coins". Coins are minted and backed by a government whereas these are minted by the actual mint which appears to be MCM (a very reputable eBay/PM dealer).

I prefer coins like the Silver Eagle or Maple Leaf but am not willing to pay $ 3 premiums and have to buy 20+ to get any sort of deal when the silver market hasn’t yet stabilized.

Simply put, if you think silver will ever surpass $ 17 again then this would be a good purchase. If you think it is going to continue to drop then do not buy.
