I am new to all of this, and don't exactly know how registries work. Should I go in the store to register or do it on-line? Is there even a difference in doing it one way or the other? I was reading a magazine today that was talking about registering and it confused me. It says that it's best to register online because then people can just purchase on-line. I assumed that whether I registered on-line or in the store, the items on my registry could be purchased in the store and on-line. Also, it said something about looking for stores that offer "completion packages" that can discount 10-20% on items that were not purchased that were on the registry. Anyone know of stores that offer this? TIA!!
