对话文本
A: How much do you pay wholesale for your products?

B: We have a few different wholesale vendors, so our cost varies a bit over the fiscal year. But the difference is miniscule, a fluctuation of about 0.2%.

A: That must impact your bottom line at least a little bit, doesn't it? After all, your sticker price is pretty much set in stone. How much do they go for retail?

B: Retail price is 29.95 per unit. We take into consideration changes in supply cost when figuring this price.

A: Is that including tax?

B: No, that's the price before tax. The tax rate is varies from different marketing areas, so it is difficult for us to figure in.

A：How much is your profit margin then?

B: Our profit margin is in the neighborhood of 20%.
