Guild Wars 2

I placed an order for a training manual but I’d like to just buy it now. Can I cancel the order I placed or if I buy it at current high seller “instant purchase” will it cancel the lower offer order I already submitted? Been reading around the forum but couldn’t find a straight answer.

Also, when you place orders on BLTC how long does it usually take to fill?

Found the answer here:
