The recently discounted RF lenses have been extremely popular — one sure indication is Amazon has been repeatedly going out-of-stock of the three most deeply discounted lenses. It looks like dealers are receiving regular shipments from Canon, though, with Amazon is showing availability in about a week for the RF 100mm f/2.8L Macro IS USM and RF 15-35mm f/2.8L IS USM. The RF 14-35mm f/4L IS USM stock will be replenished by mid-November.
Other dealers (such as B&H, Adorama, and the Canon Store) are also showing stock, while quantities last.
Seems like these are the prices people have been wanting since release.
