Alter the price for your product so you make even more money on direct sales and the margin is large enough for retail discounts.,
You should also take into account that you save money when retailers buy larger bulks and that if they promote your product sales might rise in total due to better customer awareness of your product.
In my opinion you have two possibility:
1. Don't sell to retailers and sell your products exclusively like you did in the past. Of course this could mean that the retailers get products like yours elsewhere.
2. Consider selling to retailers and adjust your marketing and pricing modells.
