Paint dog, I recommend searching "google . com" and click on "images" then enter "5 second fix." All sorts of sellers will show up including Amazon and ebay. I use this strategy for finding all sorts of hard to find items except the figurines themselves. Amazon, ebay and Walmart all have excellent and liberal return policies. You've got to be careful buying glue and products that have a short shelf-life. Gasoline to drive to a store could cost the same as the tube itself.
I recommend starting with Amazon and look for "Free Shipping" and check out the Sellers Feedback ratings. Hope this helps. GC
