Thanks to all for their input on this topic. I ordered mine online yesterday, it didn't apply the additional corporate discount. I called, the rep said the corporate discount only applied to plans/devices not accessories. Bummer, but I'll still try again and see.
Update: I called the 1-800-922-0204 number and learned a couple things: My corporate discount didn't show up since I ordered from within my company's 'profile' for VZW. BUT, if ordering through your OWN myverizon profile, the credit/discounts are supposed to show up. I did not know that.
ALSO learned about what is called a Bill Incentive Credit - depending on what your company's arrangement is with VZW, certain of those plans with VZW offer a credit for handset upgrades. Long story short, she just gave me a $100 equipment upgrade credit that I didn't know I was eligible to receive! Yee-Haw! I asked if it made any difference whether I had the handset since 4/29, she said no, and she applied the credit immediately. BIG thumbs up (for a change) for VZW!
