I've been looking into buying parts on bricklink for a fairly large battle scene MOC.

I had a look at the EB trusted sellers list and 'A Minifig is for Life'. I've noticed something odd on lots of the parts that are in his store.

Here's an example of what I mean. You'll notice that on some of the lots, under quantity there are two numbers. There's one number in bold but then next to it (in brackets) is another number with an 'x' before it. i presume the 'x' means 'multiplied by' but I'm still not quite sure what that means.

I do have an idea that for example if I buy one 'Bright Green Plant Leaves 6 x 5' for £0.20, I will get 10 of them as next to the quantity there is an 'x10'.

That is my optimistic view though

So I was wondering if anyone could shed some light on this issue for me?

You have to buy the part in multiples of the number in parentheses. It seems like that seller offers better deals if you buy in bulk.
