A spokesman said: "We always look to offer our customers unbeatable value but unfortunately this is an IT error that is now being corrected."
Dominic Gemski, 20, of Portsmouth, was so thrilled to see the tablet for such a remarkable price that he decided to buy three.
He said: "It was like music to my ears when I saw the price. I quickly bought one for my girlfriend and my brother.
"I'm a massive technology geek so I was thinking of buying one anyway. But when I saw the offer I jumped at the chance.
"I think Tesco should honour the price but I don't think they will."
After the glitch Tesco Direct and "every little helps" started trending UK wide on Twitter.
One person wrote: "Just got the confirmation email. So far so good."
In October last year Tesco stores were besieged by bargain hunters after a computer glitch saw Terry's Chocolate Oranges sold for 29p each.
The mix-up happened because the tills could not handle two simultaneous promotions on the chocolates, a three-for-£5 offer and a buy-one-get-one-free deal.
