This Electric Vacuum Wine Preserver with LED Indicator, originally $49.95, is now $9.99 at Tanga. Shipping adds $4.99, but this is still the best price we found by at least $20. This helps keep unfinished bottles fresher, longer to preserve the original taste, aroma and color. It preserves wine for up to 9-days after opening. There is a 3-Day LED day indicator (Green LED for days 1-3, yellow LED for days 4-6 and red LED for Days 7+). It is powered by only 2 x “AAA” batteries (not included). Sales tax is not charged in most states.
