I bought mine at the local Do-It Best store.
Anyone who carries National Hardware supplies should have these.
They also make all kinds of hinges, latches, universal storm door latches, etc.
The packages are white with some blue on the top with the National Hardware logo in the upper left hand corner of the package. I'll get the accurate exact part number and price of these tomorrow. If you all can't find them locally I'll pick them up and ship them to you if you want.

I agree with putting 3 latches on a 4x8 door, mine is the same size and I think I need one in the middle just for added sealing measures.
