Original text

せっかく提案していただいて申し訳ないのですが、
この価格では販売力で負けてしまい、私に利益がでません。
したがって、あなたから多く購入することができません。
Amazon.com　では＄22～＄28で販売しています。しかも、送料無料です。
Amazon.com　より安くなりませんか？
私の希望は、○○○ ＄22×15＝＄330　フロリダまで送料無料です。

Translation / English

I apologise for saying this after you went out of your way to make an offer, but at this price, I will end up losing in selling capacity and cannot make a profit.
Therefore, I cannot purchase many of this product from you.
On Amazon.com, they are sold for $22~$28. On top of that, shipping is free.
Could you sell them for lower than on Amazon.com?
I am hoping for ○○○ at $22x15=$330, with free shipping to Florida.

Translation / English

Thank you for your proposal, but I'm afraid this price is too high and I can't sell it out a lot or can't get enough profit, which means I can't buy a lot from you, unfortunately.

I saw it's sold for $22-28 on Amazon.com, furthermore, they offer free shipping.
Can you make the price down under the ones on Amazon.com?
Is it possible to make the price $22 each × 15 = $330 including the shipping to Florida?

Thank you,
