Amazon is correctly removing your reviews, because neither of your examples are things that belong in product reviews. 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)
