The very very cheapest and with the best selection is on the corner of Las Vegas Boulevard and West Sahara, kitty-corner to the Sahara Hotel, called World's Largest Gift/Souvenir Store. They have about anything you want.I need advice about Las Vegas?
Go to the Miracle Mile shops at Planet Hollywood. They have an ABC store that specializes in that sort of thing (if you are familiar with the ABC stores of Hawaii, its the same, but with Vegas stuff) If your not familiar, basically its a one stop shop for all your souvenir needs. It's kind of in the back of the mile shops
On Fremont street there are some real cheap souiveneer shops if you dont want to leave the Strip there is a shop next to MGM in teh Showcase mall that is very cheap or some shops between Wynn and Riviea (but noth worth a special trip) or has all been kindly pointed out Walgreens
There are lots of souvenir shops around, and many have fairly reasonable prices. There are lots of little shops in the area between Paris and MGM Grand on the strip, and most hotels have their own shops as well.
actually the cheapest places are off the strip at stores like longs or walgreens or other thift stores you'll pay only 25 to 50 percent of the going rate on the strip.
There is a shop on freemont St. that sells sourvniers. They had the cheapest prices compared to all the others.
