Amazon offers Prime members the 16-Piece Luminarc Working Glass Drinkware Set for $19.99 with free shipping. (Non-members can spend $35 to qualify for free shipping; otherwise, it adds $16.99.) That's the lowest total price we could find by $11. Set includes eight double old-fashioned glasses and eight coolers.
Please note this set does not include lids, as depicted in the first image on the item page.
