Joe Quinn from Quinn's Bon Bon in Salthill says they may struggle to have enough chocolate flakes to deal with the expected demand for 99s.
He told Newstalk: "We thought we'd have enough but there's such a demand from them at the moment, I don't think they're gonna last summer, but hopefully we will."
Mr Quinn added: "We'll have to start using something else and breaking up Twirl bars or start putting something into them, you know, making it look a bit better."
