Minimun Advertised Price Policy

Minimum Advertised Price(MAP) Policy

Tai Shih Hobby Corporation (TSH GAUI) has determined that its interests are best served through the adoption and enforcement of a minimum advertised price (“MAP”) policy. This MAP policy is designed to (1) protect reseller margins so that desirable pre-sales and post-sales services and infrastructure can be provided by our channel partners (2) support the TSH GAUI brand as a premium offering; and (3) avoid destructive intra-brand channel conflict.

This policy has been unilaterally adopted by TSH GAUI and will be uniformly enforced.

Policy Coverage
This MAP policy covers all TSH GAUI Partner resellers located globally.

Although resellers remain free to establish their own resale prices, TSH GAUI will, without assuming any liability, unilaterally impose sanctions as described in this policy against resellers who advertise applicable TSH GAUI products at prices below those specified herein.
TSH GAUI will not discuss any conditions of acceptance related to this MAP policy, as it is non-negotiable, and will not be altered for any reseller. MAP applies only to minimum advertised prices and does not apply to the price at which the products are actually sold, or to advertised prices higher than the unilateral minimum resale prices established by TSH GAUI from time to time.

Minimum Advertised Price (MAP)
The current listing of products and applicable MAP prices are published on TSH GAUI’s website and also emailed to Distributors/Dealers from time to time. The products and MAP may be changed from time to time at TSH GAUI’s sole discretion. TSH GAUI resellers are responsible for remaining current with MAP policy, products and pricing. Each advertisement below the MAP will be a violation of the policy.
The MAP policy applies to all advertisements of specific TSH GAUI products in and all media including, without limitation, flyers, posters, coupons, mailers, inserts, newspapers, magazines, catalogs, mail order catalogs, Internet or similar electronic media, television, radio and public signage.

Policy Violations
In the event a reseller chooses not to follow the TSH GAUI MAP policy, sanctions will be unilaterally imposed by TSH GAUI.
Violations of MAP policy shall be determined by TSH GAUI in its sole discretion. TSH GAUI will not accept any communication from a reseller who has violated this MAP policy regarding the violation or the willingness of the reseller to bring its prices into compliance with the MAP policy.

Policy Modifications
TSH GAUI reserves the right at any time to modify, suspend, or discontinue the MAP policy in whole or in part or designate promotional periods during which the terms of the policy change or designate periods of time during which the policy is not applicable. Policy modifications shall be made available on the TSH GAUI official website at http://www.gaui.com.tw

Contact Information
All questions or comments regarding this MAP policy are to be directed to the policy manager at manager@gaui.com.tw.
The policy manager shall be solely responsible for determining whether a violation of the policy has occurred, communicating decisions to resellers regarding the policy and receiving any communication regarding sanctions imposed under this policy.
