Earlier quoted context omitted.
15k orders over 20 years is on average 2 per day or 750 per year. Is that a typo?
No, it's correct.
Even if I'd replace all my store visits (grocery store, hardware store, electronics store are the main ones) with online orders, I'd probably still not oder more than once every five days (or maybe once every 10 days during covid, now that I go to the grocery store less often).
Or are you talking individual items, like you buy groceries from Amazon and every item is a separate order because they all ship from different sellers?
