Display deal

Hello all, I'm an Ardo-noob, still on the bunny-slope of the learning curve, but progressing steadily (thanks in no small part to the lurking and learning I've done here) along the blinky path to bigger things. Anyway, I came across this deal on 7 segment and matrix displays and thought I'd use it as an excuse to introduce myself here. Looks like there are 1, 2, and 4 digit displays and some 5x7 and smaller matrix in a grab bag of 50 for $10.95. If I get this right here's the link: https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&langId=-1&catalogId=10001&pa=18201&productId=18201
