Ace Teah via Amazon offers its Ace Teah Golf Umbrella in Blue for $24.49. Coupon code "ACEUMBR2" drops it to $18.99. With free shipping for Prime members, that's tied with last month's mention and $6 under the lowest price we could find for a similar umbrella elsewhere. It features a 62", dual-vented canopy, and is windproof. Deal ends September 2.
