... Amazon.com, which restricts computer returns to 30 days and charges restocking fees for fine jewelry and computers, as well as Macys.com, which won't accept returns of "special orders" --- any any ring that's not a women's size 7 or a men's 10.5 is considered a special order.

And ShopSmart notes that BJ's stores are generous with their returns, but online purchases are subject to a number of conditions.

And, check out BJs.com's order policy, which basically states that even though a product is listed online and can be ordered through its Web site, customers should not be fooled into thinking they might actually get it (emphasis mine):

Your receipt of an electronic or other form of order confirmation does not signify our acceptance of your order, nor does it constitute confirmation of our offer to sell. ... bjs.com reserves the right at any time after receipt of your order, without prior notice to you, to supply less than the quantity you ordered of any item.

Now, don't get me wrong: these Web retailers have all stated their policies ... but if you're not in the habit of checking them out ahead of time, you might be disappointed should you --- or a gift recipient --- decide a product or item is not what you expected.

Here's ShopSmart's list of the best and the worst of online return policies:
