物美廉价 的英语怎么说？

a good bargain

inexpensive in price while excellent in quality （这是别人翻译的不错）

我觉得可以这样：
products with high price versus performance ratio(性价比高的产品)

最口语也是最常见的说法.

Best bang for your buck.

不适用于正式写作.

with low price and good quality

1. filling at the price
2. with low price and high quality
3. goods with high quality and low price

可以有一下几种说法：cheap and fine;excellent quality and reasonable price;good quality and fair price。查字典真不容易。给点分吧…
