I'd never use any other online supermarket delivery service but Ocado. Their website is a doddle to navigate (even for an oldie like me!) and the checkout process really simple. There are always generous offers and also lots of offers on your favourite items that you've ordered before - Ocado try to tailor them to you. Occasionally I also receive a free gift or sample, and they always send a gift to celebrate the anniversary of your first order. Their products are of the highest quality, including their own brand, and the delivery men and women are a delight - always very friendly and helpful and willing to take your shopping through to the kitchen if desired (my elderly Aunt had a nice young man put her frozen food directly into her freezer once when she was feeling quite frail). All in all, a fantastic service and one which I couldn't do without!
