At noon on Friday June 13th, the US Mint will offer a limited edition 250th Anniversary United States Army American Eagle One Ounce Silver Proof Coin. The coin has a purchase limit of three per household, so you’re able to buy three coins per order. The cost of each order of three coins will be $315. After including the $5.95 shipping charge, each order's total will be $320.95. You can have the box shipped to your home or office and then ship it to pfsBuyerClub with a prepaid FedEx shipping label that they will provide for you. They pay you $381 - for a profit of $60.05 per order or ~19%.
To execute, first set up an account with the US Mint. Do this Monday (if you wait until Friday to get ready, it could be too late). Secondly, set up email/text reminders here. Register with pfsBuyerClub, opt in to their Army Eagle Coin deal, and make sure to understand and follow the terms. The terms are easy to follow but inflexible. Use your favorite credit card to earn cash back (in my case another ~$10). Then buy the coins at exactly noon. They could sell out within minutes.
Caveat
Such deals are available because buyers think these coins are undervalued. That judgment could be right or wrong, but if the Mint price is probably too low, it is also possible that the pfsBuyerClub is too low too. With a willingness to do more work and take on more risk, you could find a better deal.
Conclusion
I’m confident that this can work as long as the relatively simple instructions are carried out carefully. Click the green "opt in" button at the bottom of the page here to opt in to the deal. If you want to do this, do it now because they only need a limited number. More detailed instructions will be posted after you opt in. But the key points:

When the order arrives, keep the box sealed. This refers to the outer shipping box as well – don’t open the box.
