I have had grape tomatoes in the fridge that were wrinkled. I cut them up and used them in a salad. They were not spoiled, so it was no big deal.
If stuff is growing on them, throw them out. If not, eat up!
My Mom's big saying was always, "When in doubt, throw it out."
But mine is, "If nothings growing on it, eat it!"
LOL!
(Some help i am, hey?)
