I think I'm growing Tamato Berries right now in the DW if you don't get them sooner. I have to wait 20 hours to head back in.
Meanwhile, if I've already exported one to White 2, I can move it to Black and have a Pokémon hold it for cloning sometime Monday. If not, I have to transfer two from the DW Monday evening my time if they're in the inventory there. If you get them sooner, let me know and I will leave them in the DW. :)
Alternatively, we can just connect our games for trading and do a miscellaneous trade, then try to bump in the DW. You can grab one Tamato Berry from the Share Shelf when I make it available there, no DWF needed there. You can then grow some. :D I say one because the game won't let you swap for something you already have; if you plant it, however, or perhaps even put it on your own Share Shelf, you might be able to grab a second, but you have to be quick to recover it from your Shelf before someone claims it.
