Hey Wood,
No problem. Just a thing (as I saw its your first buy), have the seller give you a REAL shipping quote as 20$ is a tat expensive for a 1lbs lens. Make sure it is shipped USPS Air or Global Priority (won't make a real difference pricewise since it's not heavy and Global is way faster). If the item is shipped UPS, you will be charged OUTRAGEOUS brokerage fees (they wanted to charge me 46$ CAD for a 60$ (1lbs) item and shipping was already paid to the seller, it was simply brokerage fees).
You should check this out if you don't want any surprises. Here the link to USPS.com for rates :

Good luck
