Milk Bottle Tops (AB24)

Hi,
Thanks for looking at the post.
I am saving up Milk Bottle Tops (Plastic ones) for a charity name Pathfinder Guide Dogs and I know they really appreciate them as I received a Thank You letter.
I would be so grateful if anyone can save Milk Bottle Tops for me. The Plastic Milk Bottle Tops (Not Foil Tops).
The Milk Bottle Tops are mostly white ones and colours are acceptable.
THANKS SO MUCH and hope someone can help save Milk Bottle Tops for a great charity.
