Query: Rip Off

Great product as we all know; I bought these on Amazon last week for $50 for 50 tabs, which is twice the normal price, now it's $69 bucks for 50!!). These sellers are scum bags, and so is J&J for giving about 10 ambiguous answers as to why this product is unavailable. When it comes back on the market...if it does, all us users should never buy anything from these current rip-off sellers on Amazon.
