This wasn’t uncommon back then: we had several clients in the 90s who just couldn’t wrap their heads around how quickly many of their customers would switch to email or online forms when it saved them a few days on the transaction.
How significant their shipping catalog was in the 1990s I do not know, scaling the online storefront would have required Amazon scale investments which a dividend maximizing company was unlikely to do.

Sears discontinued its general mail order catalog (which had declined in relevance for years) in 1993, the same year NCSA Mosaic was released, while the web had about 0 public penetration and no commercial use.
So, it wouldn't have been a matter of adapting the catalog business to the web, it would have been rebuilding it from scratch.
