Big Flash sale on Comixology including the new 52 series, Barry's Wally's and Bart's volumes, Rebirth and many more https://www.comixology.com/Flash-500...WxsQ2Fyb3VzZWw !!!!!

I am going to use this sale to read more of Wally's series, but I have a limited budget. I don't have the following issues:
50-52, 55-61, 66-73, 80-90, 103-106, 119-126, 143-163, 226-230, 237-247

I can get 10 or so issues. Any suggestions?
