Unfortunately, this deal is no longer valid
Refreshed 23rd May (Posted 23rd May)
Offer showing on eBay, 500 Bonus Nectar points on £5+ spend until 28th May. Need to activate the offer. Hopefully showing for you. If not maybe check back later on today as sometimes takes longer to appear. 500 Nectar points has a base value of £2.50 but worth £5 if Sainsbury's run a double up promotion at the end of the year. Terms and conditions of the offer not showing currently but looks like it excludes gift card purchases.
