I do combine shipments, and try to remove or reduce shipping charges, when I you can send me a invoice before you pay to revise, or if you buy 2 Johnny Lightnings or any mix of diecast, I will refund a shipping charge
For Example (You can mix all types diecast brands)
If you buy 3 New Johnny Lightnings, I will refund 2 charges back to you and only charge 1, $4.24.
If you buy 4 or more Johnny Lightnings, I will refund and only charge you 2 shipping charges $4.24 x 2 or $8.48, no matter how many you buy.
