Ah, I see the ad states "bulk packaging", not retail packaging. So yes, I would assume they might look different. Memory cards are sold in bulk primarily to vendors such as phone manufacturers, camera manufacturers, etc. for them to include with their product. These have to be visually and easily differentiated from the retail counterparts.
You can generally get a better price on bulk packaged cards, but also be aware that SanDisk does not honor any warranty of these items. Only cards sold in retail packaging (or with the appropriate retail serial #) have warranties on them. So if you have a problem with it, you have no recourse but to buy another card. And that usually negates any savings you see on buying the bulk packaging item in the 1st place.
