Example I just bought all these from one seller an hour ago:
2004 JUAN GONZALEZ GAME-USED BAT SWATCH SP'100
2002 JUAN GONZALEZ INDIANS RBI KINGS GAME-USED BAT
2004 JUAN GONZALEZ TIMBER&THREADS GAME-USED BAT SWATCH
2004 JUAN GONZALEZ DUAL GAME-WORN JERSEY SP'150
Each card was $2.49 and S/H was $4.50. The way I look at is - I paid $5.49 for one card and $3 for 3 cards. I couldn't have done any better if I was patient and bid on each card in other auctions.
