X-Chef via Amazon offers Prime members the American Convex Base Coffee Bean Tamper for $7.29. Coupon code "9AJB52UJ" drops it to $4.29. Plus, Prime members bag free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.22.) That's slightly below last week's mention and the lowest total price we've seen. (It's the best deal now for such a tamper by $11.) It features two tamping sides.
