Can I buy a game in a bundle after getting a refund on the game?

I just bought XCOM 2 on Steam sale, but after reviewing the bundles that contain it, I'd much rather have the whole XCOM 2 Collection and save money on the game and the DLCs. I can't buy the bundle now because the offer is only applicable when one doesn't already have an item from the bundle.

So I requested a refund on the purchase. Will it be possible to buy the bundle after refund? And in general, is is possible to buy a game a second time after getting a refund?

Solution 1:

It turns out this is actually in the Steam FAQ:

I bought a game right before it went on sale. Can I get a refund and repurchase it at the sale price?

Yes.

If you have not already requested a refund, make sure the purchase is eligible and submit a request here.

Please note that approved refunds may take up to 7 days to process.

And indeed it did work flawlessly, got the refund within an hour and could immediately order the bundle afterwards.
