Ways to Make More From Your Sale

Want to get more from your GCOS sale? A few smart choices can make a big difference.

​

Focus on what you sell, how you present it, and how you price it—then take advantage of the seller bonuses and rewards available to you.

What You Will Learn 

​​

  • Choose popular brands and items families need each season

  • Price your items to sell

  • Give your listings the best chance of getting noticed

  • Maximize your seller percentage

  • Take advantage of GCOS seller rewards

Start With Your Best Items

You don't need hundreds of listings to have a successful sale.

​

Start with popular brands, larger-ticket items, and things families need for the season ahead:

​​

  • Bikes and outdoor toys

  • Play kitchens and larger toys

  • Popular brands

  • Stroller and baby gear

  • New With Tags items

  • Current styles in excellent condition

Think seasonally, too! For our Fall sale, shoppers are also thinking ahead to the holidays and colder weather.

 

Look for:

​

  • Toys and games that make great gifts

  • Holiday outfits and special occasion clothing

  • Winter coats, snow pants and boots

  • Cold-weather gear and accessories

  • New With Tags items that could be given as gifts

​

Get these items entered first, then continue adding inventory as time allows.

💡 GCOS Pro Tip

Quality over quantity.

​

Focus first on desirable items in great condition, presented well and priced thoughtfully. A strong collection gives you a great foundation for a successful sale.

Price to Sell

Your inventory value is not the same as your sales.

​

Price based on what a shopper would be excited to pay today, rather than what you originally paid for the item.

 

For most items, we recommend starting around 25–35% OF the original retail, then adjusting for brand, condition and demand.

Make Shoppers Stop & Look

Great listings help great items get noticed.

​

Focus on:

​

  • Bright, clear photos

  • Accurate categories and sizes

  • Short, helpful descriptions

  • An honest description of condition

 

Is it Like New? Does it have some wash wear? Is it great for play clothes? Tell the shopper.

​

Before listing, carefully inspect every item for holes, stains, tears or other defects. Your description and photos should accurately represent exactly what the shopper will receive.

Consider Half Price

Ask yourself:

​

Would I rather sell this item for half price or save it for next season?

​

If you are happy to see it sell, consider including it in the Half Price Sale.

​

Not choosing Half Price does not remove your item from the store. All available inventory remains visible to shoppers. When Half Price begins, participating items are marked so shoppers know which items are discounted.

​

Shoppers cannot see ahead of time whether an item will be included in the Half Price Sale.

Protect Your Seller Percentage

Your final percentage is based on more than simply making a sale.

​

Bringing all of your sold items and working toward a Perfect Sale can increase the percentage you earn.

​

Accuracy matters too. Carefully inspect your items and make sure your listings describe exactly what the shopper will receive.
