Absolutely agree.
For that reason I see no good reason to add unnecessary challenges. In this case the provision of merchandise. To my mind this should be very simple and lucrative for the government. They own the TT logo and can license its use. Put out the tender, in good time, and let the best bidder win. The underlying contract should be one page. Essentially ensuring that the government has the right to veto any unsuitable design.
Instead the tender is issued too late to organise the design, production, carriage and distribution to the TT. In addition huge, onerous restrictions are demanded whereby the government is trying to muscle in on the commercial side.
Hey ho. No doubt some TT T-shirts will be produced by someone somehow.
