My understanding is that purchases must be made in-store at a participating location, @sonofzeus, which, sadly, eliminates the bonus CB… 
The sales associate that I spoke to in-store believed that only in-store purchases were eligible for the rebate, @sonofzeus, and showed me how the receipts differ:
store receipts start with H, then the store number and transaction number (H1234-12345)
online receipts start with W (for warehouse?) (W987654321)
Accordingly, I would expect that HD uses the store number in the receipt code to determine whether a purchase qualifies for the rebate match…
I’d be very interested in learning if an online pickup order qualifies for the rebate match, despite the fine print indicating otherwise… 
I placed an online order two weeks ago where part of my order shipped free, and part of it was in-store pickup (not available at the store, but too heavy to ship to home for free); the CB portal that I used clearly stated that in-store pickup or payment via HD gift cards would void my CB (both of which I was doing, at 100% GC), so, I didn’t expect to get any CB out of the deal…
Amazingly, I received an email the next day informing me that I had earned $30 CB from my purchase (pending for 45 days, of course)!
So, maybe there’s wiggle room with HD, too…? Order online, pickup in eligible store?

@ZenNuts asked:
It says can’t use target GC to buy 3rd party GC on Target.com, what about in store. Has anyone tried it?
The absence of the specific language “in-store” when restricting the use of Target GC’s as payment tender to purchase 3rd-party GC’s has led curious shoppers to attempt to purchase such in-store; despite numerous reports about how Target has recently changed its policy disallowing 3rd-party GC purchases with Target GC’s as payment tender, there have been a few reports of successful purchases of eBay, Disney, Starbucks, Xbox, Chipotle, Regal, and Lowe’s GC’s within the past few months.
Whether the reason for such low reporting is due to limited success (YMMV) or simply to limited attempts is unknown.
I think Target is running behind: my e-GC’s arrived at 12:08 p.m. CT, despite being scheduled to be active two hours earlier, at 10:00 a.m. CT…
ETA: 1:42 p.m. CT: just received confirmation that my e-GC’s have been “shipped”.
