I purchased item which would not hook up to my computer without having to purchase another item for $30 to make the connection work. Went to the store where the employee was able to help me better. Bought item with correct connections from the store, no hassles. Hard to purchase online when you are unfamiliar with the item and nobody is there to answer your questions. Then, it's a hassle returning the item (have you seen the lines at the Post Office? That is enough to make you think twice... they are cutting back on their help at the Post Office...) Do you have an hour to waste standing in line at the Post Office, or would you rather pay $10 more at the store and get the correct item to begin with! Who in their right mind uses the Post Office to send stuff nowadays anyway!This experience discourages me from buying anything online. Plus, if you return an item to the store, you get a FULL refund, no deductions for "shipping", i.e. standing in line at the Post Office to return the item.
