FWIW, almost every [negative, because I'm trying to warn others about wasting money] Amazon review I leave is removed for arbitrary reasons set out by Amazon. They seem uninterested in contributions like "this mouse was $30 not 6 months ago, and the current $90 price tag is unconscionable. [LG G602 mouse]" The few times I've complained about shipping problems (as you suggest you've seen) they also removed those.
Do not leave price related reviews. The prices change daily. You may leave a bad review because you think the price is too high. Tomorrow the mouse may cost $10, but your one star review is still there ten years later.
Shipping problems do not belong in product reviews. The listing is for a PRODUCT, shared by any number of amazon sellers. Amazon provides seller reviews to comment on seller's shipping problems. (If you are leaving these as seller reviews, then I apologize for assuming, and you are correct)
You telling me the mouse was cheaper before doesn’t help me decide which mouse to buy today.
