Money saving tip at pick a brick

In any good classic space or neoclassic space diorama, one has to have caution tiles with chevron in yellow and black...i.e. all wings of the original 924 and 928 have this on the wing.  So I was thrilled when I saw a tile that would be perfect on a diorama of a hangar with gray floor. It was on pick a brick as shown here

Since I was buying pieces all on bricks and pieces, I typed this piece# in and this came up

So the piece was almost 1/2 off on the pick a brick vs bricks and pieces.  The 1x2 trans yellow plate was .08 vs .10 on the two different buying areas...so fortunately you can order from both pab and b+p but it may pay to check!
