It was only after the pair had handed over their cash they realised they had splashed out for a bag of bottles.
Instead of a cutting- edge Apple device, the man and woman were left with worthless rubbish.
Police are warning others not to be duped by the conman.
Officers said the couple were approached by a man selling cut-price iPads in Stratford Street, Maryhill.
He showed them what is believed to be an authentic Apple iPad and they agreed to the purchase. They were given a bag, which they were told contained their new gadget.
However, it was only later, when they opened the bag, they realised they had been duped.
Police warned people to be vigilant and not to be taken in by the scam.
A Police Scotland spokeswoman said: "A man offered the couple an iPad. He showed them a real iPad, and an exchange was made.
"An investigation is under way and inquiries are ongoing."
