Help needed to source ingredient - Chinese Pancakes

Does anyone know where to buy Chinese pancakes for crispy duck without having to buy a meal kit including the duck? I was told they were available at Waitrose but I cannot find them, not even through online shopping. I can find packs of 100 or 1kg online at specialist Chinese grocery suppliers but I only want enough for 1 meal.

Ask at your local Chinese takeaway shop!

Ah, that makes sense! Thanks for the idea.
