I have just had a similar thing happen, as I have today purchased

Flinks Instant Meadow 2 - Winter 5

Flinks Winter Trees

Flinks Conifer 2 

I was able to purchase these items as they were purchased in a bundle on 28th October and they didn't show up as already purchased.

Am I able to get a refund on these items, and if so, what do I need to do?
