It depends. Sometimes I like browsing just for the sake of browsing, with no intention of buying anything. That is relaxing. If I want to buy something and have to go looking for it it can be relaxing, or it can become tiresome and disappointing depending on how long it took to find the merchandise in question or if I found what I was looking for at all. If I need to buy something and the shopping experience is anything less than commando-style (get in, get what I need, get out ASAP) it feels like a chore. That is not relaxing.
