The Certified Partnership Program here at Freelance Electronics is a program to help our
customers have access to more products from Freelance vendors that have been screened and
vetted. CPP vendors will have proper certifications and procedures in place and that
are equal or exceed the Freelance certifications. The CPP vendor must also match our
core values and have the capability to ship same day or next day if after the shipping
cutoff time of 2PM. All CPP vendors will ship from their own stock. All orders come with
the same 90 day warranty and comes with a money back guarantee if quality is not met in your
inspection process. All CPP vendors are located in the Continental US. The FOB will be
identified by shipping area. (West Coast, Mid West or East Coast)
On all Bulk Freight Orders, there will be a one time shipping fee no matter how many CPP
vendors your order is shipping from. Because of multiple shipping location zones, all orders
will be delivered in 1-6 days maximum.
