This is a typical night market in Thailand with the usual constellation of Thai souvenirs and apparel. You should absolutely expect to bargain with the vendors. Anything not already marked with a price means that it’s subject to negotiation, and although you might think that you don’t mind overpaying for a few goods since nothing is actually expensive, you’ll eventually get tired of paying two and three times as much as everyone else for the same goods. If the vendor immediately agrees to your offered price, you did not go low enough. You are going for a vendor who has to think for a while, consult someone else for your offered price, and just barely lets you walk away from the sale before the price is agreed upon. If they let you walk away, you’re too low, at least for that vendor. Plan to pay in cash. Even if the vendor accepts credit cards, they will usually add a 3% surcharge. And bring your own backpack to put your parcels in. They will give you bags, but eventually you’ll get tired of carrying the numerous parcels and you’ll want your hands free to browse. Also bring your own water, but be aware that there are numerous stalls nearby with street food as well. Bathrooms are nearly nonexistent, and you may need to pay 5-10 baht to use one.
