Get a variety of sweets like marshmallows, candies and much more.
Can I write much 'more come' if I have already written 'like' before it???
Not a teacher.
I don't see why not. It sounds ok to me, it sounds like you're advertising something. Just a slight note the sentence starts abit abrupt. Perhaps 'such as' would be a better replacement if you are unsure.
Advertising a sweet shop - 'Come get a variety of sweets such as marshmallows, candies and much, much more!'
Maybe telling a friend what you can buy - 'You can get a variety of sweets such as marshmallows, candies and much more.'
Hope this helps.
