In your case I think Direct Links would be preferable, rather than Hop Links. This provides your affiliate with code for a direct purchase button they can copy and paste into their own site, where they earn a commission on each order placed through that button. Buyers who use that button would still be purchasing directly from you and paying you in full, then you would pay out commission earnings to the affiliate, typically as a monthly lump-sum via PayPal.
In your E-junkie Seller Admin > Affiliate Program Settings, you can leave blank the Common Affiliate Share, the Common Hop Link Landing Page URL, and the More Information URL fields, and also untick the box for List affiliate program details in E-junkie Marketplace and your E-junkie Shop, then click Apply in that section to save changes.
Further down, under the Product-specific Affiliate Settings section, select a product that the affiliate will sell for you. You can leave Product Hop Link Landing Page URL blank, but do enter a Product Share % which that affiliate will earn on their referred sales, and tick the box Enable Product Direct Link, then click Apply in that section to save changes. Repeat this for each product the affiliate will sell.
