I didn't bother to learn about ramping because I hate 3*AAA flashlights so much, but I do have some good news. I got a full refund through PayPal, no thanks to VolumeRates. Also, I noticed on VR that the flashlight is out of stock, but it's still "available" on DX. I hope that DX fixes that description soon. Good luck to everyone with the PayPal disputes!
