I will NEVER order another thing from O-P. Their website is VERY misleading and customer service is awful.
I had placed an order beginning of last year. I don't remember all the detail now but everything showed "in stock" when I placed the order, but in the email I got after paying stated some stuff was out of stock, unknown delivery time. I gave it a couple weeks and stuff started filtering in.
Shipping was around $23-24 if I remember right, anyway. They hit me with close to $100 for shipping before I caught it. THEY CHARGED MY CARD SHIPPING FOR EVERY ITEM!! Since it all shipped separately, they wouldn't refund my money unless I returned it all! So, I did, and it took another month to get refunded. Never again
