Prices are going all over the place right now for this one! I've been watching the sales in around 3.0-5.0, since I'm currently in the market for one. According to GPA sales for October-November, sales were:
CGC 5.0
November 4 @ $5520
November 1 @ $8995 ($2k higher than the previous GPA sale, wow)
October 25, 2018 @ $7000
October 7 @ $6700
CGC 4.5
November 3 @ $1399 (someone got a good deal here)
October 4 @ $5000
CGC 4.0
November 4 @ $6000 ($1k higher than previous GPA sale)
CGC 3.5
October 7 @ $4800
How much higher can this go? I feel like I'm being left in the dust here as I'm waiting for the right one.
