Short answer
Go to the Monday night weekly market (Central Textile Market area and Ashokapuram) to buy direct from manufacturers at bulk prices. Go to Texvalley for about 1,600 showrooms open every day, with warehousing and logistics. Many buyers do both.
The Monday night weekly market brings manufacturers from Erode, Tiruppur, Coimbatore, Namakkal, Salem and Karur together for one night. It is best for buying garments, dhotis, sarees and cotton textiles direct at bulk prices.
Texvalley is a modern mall with about 1,600 showrooms, open daily, with warehousing and logistics on site.
A common plan: Texvalley by day, then the weekly market on Monday night.
