Any experience with Donruss Redemptions?

I have two autograph redemption cards from the new 2007 Donruss Elite football release.
I was wondering if anyone has dealt with them recently and can tell me:
1. In your experience, do they ship back the cards in a timely manner?
2. Do they "usually" ship what you are redeeming, or is it like my only experience with Upper Deck where they send replacements instead because they can't send what they promised on the redemption card?
and my "main" question:
3. Is it going to confuse anyone at Donruss if I send both redemptions in the same envelope? Or would it just be safer to send them in seperate envelopes?
Thanks for any insight into what I should expect.
I'm very new at dealing with modern redemption cards.

I collect Vintage Cards, Commemorative Sets, and way too many vintage and modern player collections in Baseball (180 players), Football (175 players), and Basketball (87 players). Also have a Dallas Cowboy team collection.

They charged 19.95 per artwork for postage and wouldnt combine shipping because they claimed that each artwork was sent in an individual packing box. I sent in groups of 5 at a time and they still mailed everything in one box.
They dont mind the sending them in in one envelope, but if you need to include return postage for the cards they will want you to include the proper postage for each card.
You will get your redemption and expect 3-4 weeks for your cards to come back.
Other than the postage gouging, I have had no problems with Donruss/Playoff redemptions

<< <i>Not to hijack, but this reminds me, I have had a Topps Auto redemption from the 06 rookes set out for about 4 months now. Does anyone have any tips on how much longer I will be waiting? >>
I still havent received 2 2001 Football archives auto that were sent out in 2002. I quit running out to the mailbox in 2005....
