This persistent meme commits the fallacy of believing that every person follows the precise same fact pattern as yourself: Buying a fridge on some predictable, perfectly recurring and invariant schedule.
In fact, it is probably far more likely that a person who just bought a fridge will be favorably economically incentivized by an ad for a fridge than a randomly selected person.
For one thing, we know that this is a person who will ever influence a decision to buy a fridge (because they in fact did buy a fridge). Many people will never select a fridge in their life (for reasons that include renting a home, moving into a home which already has a fridge, replacing a non-working fridge with whatever a repairperson selects and is thus not influenced by an ad, is not the person in their family who selects a fridge, etc.)
A person who just bought a fridge is more likely to return that fridge and buy another than a randomly selected person is likely to buy a fridge in the same time period.
A person who just bought a fridge is more likely to be a decision-maker in selecting another fridge in the near-term than a randomly selected person (for reasons that include: buying another fridge for their garage, buying one for their business, recommending one to their contacts).
Buying a fridge is a rare event that probably absolutely correlates positively to buying another fridge.
