Headlight Question

I just ordered the Toyota 81110-60P70 retrofit kit, partly because its hard to believe it's that inexpensive: $27.44 shipped from toyotapartsdeal ($16.49+$10.95 shipping). It includes housings, bulbs, and a wiring kit w/relays.

The door windlace/welt/weathercord for the same car, shipped from RockAuto, was $9.90 more. Sheesh.

This is possibly the no-brainer deal of the decade.
