A fun anecdote from my wife: 6 years ago she reviewed a nursing bra on Amazon. Gave it five stars. Fast forward to now and she when pulls up her review history that same review (with the exact text!) now appears on a consumer electronics device.

Yup, it's a very common way to get a product with high sales and ratings. You put up a low cost, high volume, high quality item. Sell it cheap, then after you have enough 5 star reviews, swap all the pictures and text with a new higher margin (maybe lower quality item), completely unrelated item.
