I went to Target in Baldwin Park, CA and I saw the TI Graphlink for clearance for $11.90, when I rang it up it was for $3.90. So I bought 10 of them. It seems like that TI discontinued these for a newer version that does exactly the same things just different design. You guys should grab them when you can. These usually sell $20 retail. I also heard from a friend that TI is discontinuing the TI-92 graphing calculator and he bought his for clearance at Office Max for $50.00. Keep your eyes open for that!!!
