These have been rather hard to find on Amazon at all, let alone under $100. I haven’t seen these sold anywhere else in the last few months for anything close to this price. Don’t forget, these come with the SPD SL cleats, as well, and those cleats are now selling for about $31… even on sale, the price is still $25 for genuine Shimano. So, if you figure $30 value for the cleats, the 105 pedals are only $70.
