I'll offer the counter anecdote. I've order thousands of food items off Amazon over several years and have had zero issues with expiration dates. I check any food item I think would cause me illness from being expired.
Expiration vs. freshness. When I buy coffee or anything at a supermarket, the expiration date is about as far into the future as you can get. When I order on amazon, it's always much shorter. Coffee is a great example. It's usually months fresher if I buy in store. Not an issue per-say but you are totally buying the end of life stuff.
