When comparing the pricing of the two sunglasses, you’ll find that they are pretty close – just over a $20 difference between the two. Costa Del Mars sunglasses are, on average, about $187, although this will vary depending on the lenses and frames you buy. Maui Jim sunglasses, on the other hand, are over $209 – again, depending on the style you select and where you buy from. Although Maui Jim sunglasses are more expensive, it would be tough to make a selection based on price alone.  There’s not a huge price difference between the two – both are costly pairs of sunglasses.  It’s hard to say that Costa is a better buy just because of the price alone, but that is something to consider, particularly if you are a bargain-shopper.
