İSTOÇ (Istanbul Wholesalers' Market) is one of Turkey's largest wholesale trade centres, located in Bağcılar and home to hundreds of businesses. From gift items to textiles, electronics to toys, a huge range of products is concentrated in a single area. Here's a practical guide for retailers visiting İSTOÇ for the first time.

Layout: blocks and numbering

İSTOÇ is divided into "blocks" (ada), and every business has a block and unit number (for example, our store is at Block 9, No:51). Noting the block/number of the company you're visiting in advance saves you a lot of time in such a large site.

When is the best time to go?

Traffic at İSTOÇ tends to be lighter early in the morning and on weekdays. Both foot traffic and stock pressure on certain products increase around seasonal transitions (summer/winter changeover) and before public holidays — planning ahead helps.

Negotiation and minimum orders

Wholesale pricing is generally tiered by order quantity. Terms vary by business, but most sell by carton/pack and don't offer single-unit ("open") sales. Clarifying the catalogue and minimum order terms on your first visit saves time later.

Shipping outside Istanbul

Many wholesalers at İSTOÇ ship not only within Istanbul but nationwide across Turkey. If you're based outside the city, it's worth asking in advance about a supplier's shipping coverage (which provinces, which courier) — this lets you source regularly without needing to visit in person.

Choosing a supplier by product range

Some İSTOÇ businesses specialise in a single product category, while others (like us) offer a wide range across several categories. If your needs span multiple product groups, working with a supplier who can cover them from one place saves time and simplifies logistics.

How to spot a reliable supplier

Google reviews, years in business, and genuine customer engagement on social media all give useful signals about a wholesaler's reliability. Keeping your first order small to test quality before committing to a long-term partnership is a sensible approach.
