Lowes out of humidty domes whats a backup?

My seeds are germinating right now i went to lowes to find a humidity dome but they are all out im wondering what i can use that will work just as good will plastic wrap do it or what will?

I have used plastic bags and zip locks with air holes and spray inside

i have also made a humid dome out of a large warhouse cerial box and ceran wrap ( cut out most of box keep corners and edges cover in plastic wrap try it

have used large soda bottles cut in half

come on be creative
