Maybe I don't know enough about recommendation systems, but surely not? If I buy a kitchen table, in my demographic (mid-20s in rented accommodation) it's because I moved into a new flat, or my existing table broke. In either case, buying a new table actually marks the start of a long period where I won't be buying any new tables, and every day from then onwards I'm slightly more likely to buy a table.

As far as I know, buying a kitchen table is so rare that the unlikely possibility that you return it, it breaks, or you are a "serial mover" that rents homes for small times can be enough to make the odds of somebody that just brought a table buying another higher than some random person.

Unless you have some aggregated market data, you don't know either. Up to very recently, nobody knew if the likelihood increased or not. Nowadays a few people are able to discover it, but it doesn't look like they bothered to.
