Today only until 10 pm ET, eBay cuts $15 off orders of $75 or more sitewide via coupon code "PSAVE15NOW" when you check out with PayPal during its Flash Sale. Coins, paper money, eBay gift cards, and real estate are excluded. Other exclusions may apply.
Note: The coupon can be used once per PayPal account within a single transaction (or cart), while supplies last.
There's a less expensive way, and then there's the way that works for you. The two may not be the same.
