Is the eruv valid when the baker explicitly names the payer and performs zikui (conferral) on his behalf through a third party?
Synopsis
The Shulchan Aruch and most poskim hold that if the baker explicitly names the payer and transfers the eruv share to him via a third party (zikui), the eruv is valid. A minority opinion (Tosafot as understood by some Acharonim) disagrees, holding that the payer's initial intent to purchase with money vitiates all subsequent conferrals.
