Candies, Candy

[Noego]

Hello everyone,

When is it appropriate to use the plural form of candy?

I've never heard candies before, until I came to China. I've had people using candies a lot.

For instance, suppose it's raining outside and you're selling candy.

I would say:

I'd better get inside, the candy will get wet.

Rather than:

I'd better go inside, my candies will get wet.

Can both forms be used?

If so, are they both colloquial?

Thank you in advance.

Both are fine to use - candy is general [and could refer either to a whole stand of sweets or could be a block of chocolate or a bag of toffees], candies is specific - lots of single sweets.
