As everyone said, given the type of product this is, you need to get the new one before you can return the old one. Also, i want to see the T’s&C’s on the certificate before going to the time and expense of shipping the old one back. I may end up not liking the offer. The website leaves several unanswered questions.
I opened a ticket as WD said to do. They said they would respond in two days. Four days later, no response. I took the suggestion in this thread and did chat. Got right in, no wait. The guy said he would send the offer before I had to return the drive. I got the RMA, not the purchase offer. Second chat. A few minutes wait, but not bad. Had to explain the situation again (even though she had my RMA number). She said she would escalate the issue and I would get my certificate by email within 24 hours.
Someone mentioned the offer seemed to change over the weekend to require shipping the old device back, first. I think I see another change in that they seemed to originally say I could buy it from an authorized dealer. I am not seeing that wording any more. I prefer an in-store pickup situation rather than shipping from WD.
I am of conflicting opinions on all of this. The right thing for WD to do is to make a correction to the OS. As others have said, some companies have a history in doing this. Having been in product development in the past, I understand about declaring a product at EOL. The long term support costs can be enormous. WD seemed to drive down the middle path with the 40% off offer. This does not make me happy, but OK. Subtract one point on customer service.
I also qualify for a 15% discount. You can get it if you are a senior or if you return a drive. You have a returnable drive in your box, so you get the deal. WD pays shipping on the return drive. Bonus.
WD is only allowing us to get the older, smaller, systems. Deduct a second point for this. It might be that they have excess systems on hand and this seems to be a way to dump them while building PR points. This bit of cynicism is probably unwarranted. Just look at the deal.
We have to pay for return of the old drive. Deduct a third point. $10-20 off the value of the deal. Might have to pay to ship the new product. If so, deduct a fourth point.
I ran the numbers using MSRP. If you go to with 8TB EX2, the deal saves you $141 minus the cost of purchase shipping. Not bad. You can buy two at this price, so 16TB (albeit, in an inconvenient package), all told, costs just under $500 compared to the 16TB with 15% off at $600. If they would let us buy the 16TB version on the offer, it would only be $420. That would be a nice deal.
This is a pretty good offer, but certainly no slam dunk. I will be looking at other companies for comparison. I expect I will end up taking this offer.
