How can I tell whether a location will pressure me to buy more?

Four steps: Pay attention to the "sales promotion, prepaid plan purchase, and addition of items" feedback in the negative reviews (the evaluation is third-party information and needs cross-platform verification); do a single experience first and observe the intensity of the sales in person; call before going to the location to ask "Will the price increase when you visit the location, and will the treatment be promoted?" to see if the other party dares to answer clearly; give priority to institutions with price disclosures, per-session support, and transparent refund and change rules.

Filter out two or three companies based on these items and choose the best after a single experience. buying a prepaid plan always comes after you are satisfied with the experience.
