Parent gifts

Hey all! So we are thinking of parents gifts and just wanted some ideas from people about gifts that won’t break the bank! Also my parents r paying for the plates for our 200 person wedding, fiancé’s mom and step dad who raised him are helping out a lot. His dad and step mom are coming as guests and their dad and step mom of the groom role, but not involved in the planning what so ever, just excited to be there! Should we get them a little something too? I’ve read parent gifts r for them to thank them for their advice and help, and his dad and step mom who we r close w wouldn’t be upset if they didn’t get a gift (we r gonna give them in private anyways) but should we still do something for them!? Too much thinking and trying not to stress, any advice would be welcomed.. thanks!
