I am sure she is a lovely person 
I am worried now in case she is Mumsnet Royalty or something.
MM most wraps can be used with most two part nappies, ie those with an inner soak bit and an outer wrap. There are other types, like all in ones, or pockets, which do not need an additional wrap. Some are sized, some are multi sized with poppas to make them fit smaller bots. They vary greatly in quality. Blueberries are awesome, but pricy. Motherease wraps have a good reputation, and if they are rikki or airflow ones, then they are awesome, and I would buy them off you! I never liked the liners much, preferring fleece, but again that is personal preference.
That seems like a very good price. Ask to have a look at them, and ascertain how old they are as older wraps can perish, and how much use they have had. Take a teddy or doll to try one on, and see how you feel. If they look yucky, do not be scared to say no thank you. If you did not get on with them, you may well make more than that if you sold them on.
Washables are complicated. No question is silly.
littlelolly it is so frustrating being so near and yet so far away from the jab.
Mummies, please do be persistent about this. The nearer to 34 weeks we have the jab, the greater chance of it protecting our babies. Even if babies arrive early, they will be protected to an extent as we are protected. If babies are late, then they have even more time to absorb the good stuff. Do not be fobbed off. We are special cases (were anyway) and need priority treatment, even if it does inconvenience them.
