I agree.
Inflation rate is one thing. Other things could be changing that often exceed the oft-cited rate of inflation: rent/utilities, health insurance cost changes or plan changes, materials/supplies cost, equipment replacement, shipping/supply chain costs, onboarding more new employees than expected, IT/software. Especially with small companies, these changes can be felt at a magnitude. If the company is affected by tariffs changes and considering the introduction of so many new designs this year, or this, or that... you never know what's exactly happening, and there's more to a business. Even with "simple" changes like adding O-rings, costs can add up: the O-rings themselves, labor/time to sew them, let alone quality control, training and informing everyone of the changes, and other behind-the-scenes stuff.
Yes, sometimes TB bags can seem like a significant price and I am sure there are members who are buying now to save the $5-10 before the price change. But putting your dollar where your mouth is and supporting (American and/or) ethical businesses and ethical manufacturing is important to a lot of members. The steadfast quality and the level of customer service here aren't on Amazon. TB takes pride in allowing customers to know staff by name, see pets, be welcomed to the factory- they'll make cookies. The four months of advance notice for minor price adjustments is extraordinarily kind. The elaboration about specific minute design changes is not many places at all.
You'll see sustainability through the shipping carbon offsetting and encouragement to mend bags rather than replace. Collaboration/communication with customers on a level you won't see elsewhere. Relationships built, designs changed, generosity, inclusion. Fair and living wages and benefits - which are not cheap and are often the bulk of expenses for many companies.
I have started to forget now but I've had many a backpack rip and tear on me, zippers fail... money poured into replacements. I'm not worried about if that happens to me anymore. I'm looking for longevity and to reduce that 'fast fashion' mindset where everything is 'replaceable.' I'm not saying everyone here is looking for an ethical company, sustainability, or these ideals I'm talking about. But there's overlaps of groups of folks who agree that TB products fit their lifestyles and values. Minimalists, quality freaks/BIFLers, sewing fiends, bag lovers, lucky gift recipients. Many people here who come for the bags or bag questions and stay long after the question has been answered. You get what you pay for and there's many reasons for the loyalty.
