Tom uses Playtex Straw cups and I have been going crazy since Playtex no longer makes replacement straws. Other board members have shared an online source for them but I thought they were too expensive since you get one long straw and two short straws in a pack for something like $2.69. Since I only use the long straws, I couldn't justify spending $2.69 for one straw! Well, last week I saw some Rubbermaid straw cups for adults in the grocery store and bought one to see if Tom would like it. He doesn't, but there was an order form inside the cup for replacement straws. The cost was only $1 for 20 straws! The straws are a little longer than the Playtex straws but can be easily cut to fit them. I wrote down the address before mailing my order form. If anybody is interested, I will be happy to post the order address here.
