21 tooth 12 dp spur gear

The 21 tooth 12 DP gear I bought arrived very quickly. It was exactly what I needed to fix my RV slide out. I had to machine it to fit, but I knew that when I ordered it. VERY SATISFIED!!!

When will I be charged for my order?

Do you provide credit terms?

Can I get a discounted price? I am a reseller / government entity.

What is the return/warranty policy?

Can it be shipped today?

Does “Usually ships in 24 hours” mean it’s in stock?
