I can not answer re: Dec 26th... HOWEVER, I did use Riteway for the first time this past October, and provisioned for a 2 week trip (minus produce and most meats). I was highly impressed as they arrived about 0830 to Sea Tiger at TMM base (As scheduled). We closely verified the delivery and 99.9% accurate (! fruit juice was different brand than ordered). This included beer, wine and some booze).

If I were going to be needing on a holiday, I would definitely provision to avoid potential "store closed". I believe the reputable outfits would not take orders for the delivery date if they did not feel they could fulfill order (Yes, I know, Island Time)... I would also call and inquire.
