-        // Current logic: Creates one section with all coupon sets
-        // 
-        // Future enhancement: Filter coupon sets into different sections based on categories
-        // Logic:
-        // 1. For each couponset, get its merchant_uuid
-        // 2. Find the merchant with that merchant_uuid in self.merchants
-        // 3. Get the merchant's category_uuid 
-        // 4. Find the category with that category_uuid in self.merchantCategories
-        // 5. Group coupon sets by category
-        // 6. Create separate sections for each category
-        //
-        // Example structure after filtering:
-        // - Section: "Εκπαίδευση" (Education) - coupon sets from education merchants
-        // - Section: "Ψυχαγωγία" (Entertainment) - coupon sets from entertainment merchants
-        // - etc.
-        //
-        // Implementation steps:
-        // 1. Create a dictionary to group coupon sets by category: [String: [CouponSetItemModel]]
-        // 2. Iterate through self.couponSets
-        // 3. For each coupon set, find its merchant and category
-        // 4. Add coupon set to the appropriate category group
-        // 5. Create a SectionModel for each category group
-        // 6. Sort sections by category name or priority
