Aftermarket and 3d print having an effect on GW?

[twopounder]

I was browsing GW's bitz section, and many of the prices seem to have fallen. Maybe my memory is just fuzzy, but I recall jump packs, shoulder pads, and weapons being much more costly. I think I paid around $20 for 5 jump packs some 5ish years ago. Now they're $8.50. I know this is the area that aftermarket sellers target pretty heavily.

 

Has anyone else noticed a dip in these prices? Do you think it might be related to competition springing up? Am I just old with a failing memory? :unsure:

 

Edit: Just realized this should probably go in the general area. That's what I get for posting with no sleep ;)
