(For your information, to reserve something is to hold it for someone and not sell it to anyone else, waiting until that person has enough to afford it.)

First of all, I'd like to reserve a pair of Fancy Mecha Wings, for 600 CE as soon as I have obtained it.
I would also like to reserve Heavy Glasses. This is for 1250 CE.
[Note: Depending on whether or not I get enough for the Heavy Glasses by a certain time, I might not want them.]
