Buying from the side shop, buys from main instead?

Hey, just a quick question: I've had this happen a couple of times where I'll go to the side shop to complete my upgrade boots, and I'm not sure if this is the case, but if I have the shop menu already open and walk into the side shop and by the item I want, it will buy from the main shop instead and put it in the stash forcing me to either sell it and farm some more to buy it again, or run back to base to grab an item I thought I would get from the side. I.E Blades of Attack to combine into Phase Boots.

Is this a thing, or am I doing something else horribly wrong? Because it seriously ticks me off when the item I want is bought at base instead of at the side where I need it quickly.

Just close the shop window and open the sideshop window. =/

Figured as such. It's little asinine WC3 DOTA design remnants like that that annoy me. If you are at a shop with a menu open, buying the item that is also available at that shop, it should just give you it there. Game is too fast-paced to punish fiddly menu errors like that.

Anyway, thanks for the answer. Thread over, I suppose.

I agree, go to Playdota and make a thread on this, maybe they'll consider it. I get equally annoyed by it.

side shop not selling everything, if your item must buy at base, use courier(make sure your middle not using it, they need it)
you can sell your item within 10 sec(or 15 sec)with full price, so if you found that it is on your stash, right click, sell, and find out what was happen
