Having consulted the online dictionaries, I tried to come up with a French phrase for 'As if I could find them in just about any shop!', but I can't think of an appropriate phrase describing the difficulty in finding some sold-out products which my friend would like to get her hands on. I would like to say a thing like this.
As if I could find them in just about any shop! I'd like to make her happy, but going all over the city to look for them?!
