You definitely need to get samples of any garage flooring before you order it! You also need to consider that garage floor tiles are NOT a one size fits all products. I know that we send samples of garage tiles out for free. Personally, I like the Swisstrax brand.
If it is a "Deal" you are looking for, we get closeouts all the time. A major garage franchise dropped a line of tile and we are selling it at $1.75 a sq. ft. because it has their logo. We sell tile from the exact same mold without their logo for $2.89 and it usually cost me more than 1.75.
That said, buying garage flooring because it is a deal is kind of like stocking up on milk when it is on sale: It may leave a sour taste in your mouth. Call a company who has more than one tile. Explain to them what you are looking to use the tile for and ask them for suggestions. If they are good at what they do they will have a different suggestion depending on what your use is. If your just parking your car, buy the clearance stuff –after you see a sample.
General considerations: Should be at least ½” thick and should allow for moisture to flow freely underneath the tile. You also need to understand the locking system and how likely it is (or is not) to come apart.
