PSA: please DON'T pay more than MSRP for Afterbirth+ on #NintendoSwitch. While the first run is limited, it's still available. 1/2— Tyrone Rodriguez (@tyronerodriguez) March 19, 2017

Some people are having trouble finding The Binding of Isaac: Afterbirth+ at retail, but the copies are still out there. You just have to be willing to hunt them down. Resellers are offering up their copies for a good amount above retail price, and it's clear some people are biting. Just take the time to do some shopping research before biting the bullet on these higher-priced options.
