I shop fortnightly because there is just me and the cat, and I can't manage to need enough in one week to qualify for a free delivery every week.

Lately I have been using Sainsburys and Ocado, because Asda specialise in junk, and Tesco vouchers are such a small reward for my custom.

Last week I still had ample stocks, so resisted a 15% off offer from Ocado because I didn't have enough storage space to put it in.

This week I opted for Sainsburys free midweek delivery, and at the 11th hour I got a mail from Ocado offering 15% off again for and order placed for this Tuesday or Wednesday.

I decided to let the Sainsburys order stand, and was glad I did, because it was 10 minutes late so I got a £10 off free voucher for next time.

By letting Sainsburys and Ocado compete for my custom I am getting free deliveries and discounts which are worth more than the Tesco clubcard vouchers I used to get.

I used Tesco deliveries for many years but they have got complacent and lost their competitive edge.
